To ensure proper target selection the NGX_MACHINE variable is now set
based on the MSVC compiler output, and the OpenSSL target is set based
on it.
This is not important as long as "no-asm" is used (as in misc/GNUmakefile
and win32 build instructions), but might be beneficial if someone is trying
to build OpenSSL with assembler code.

Output examples in English, Russian, and Spanish:
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01 for 80x86
Оптимизирующий 32-разрядный компилятор Microsoft (R) C/C++ версии 16.00.30319.01 для 80x86
Compilador de optimización de C/C++ de Microsoft (R) versión 16.00.30319.01 para x64
Since most of the words are translated, instead of looking for the words
"Compiler Version" we now search for "C/C++" and the version number.

Wildcards for msvc in NGX_CC_NAME tests are not needed since 78f8ac479735.
|
|
By default, MSVC uses vc<version>.pdb in the current directory.
With the "-Fd" switch it is directed to be in the objs directory instead.

While 325b3042edd6 fixed it on MINIX, it broke it on systems
that output the word "version" on several lines with "cc -v".
The fix is to only consider "clang version" or "LLVM version"
as clang version, but this time only using sed(1).
|
|
As per POSIX, basic regular expressions have no alternations, and the
interpretation of the "\|" construct is undefined. At least on MINIX
and Solaris grep interprets "\|" as literal "|", and not as an alternation
as GNU grep does. Removed such constructs introduced in f1daa0356a1d.
This fixes clang detection on MINIX.

Oracle Developer Studio 12.5 introduced GCC-compatible __sync builtins.
Unfortunately, these builtins are neither GCC-compatible (they generate
warnings when used with volatile), nor working (unexpectedly fail on
unpredictable combinations of code layout and compiler flags). As such,
the gcc builtin atomic operations configure test explicitly disabled when
compiling with Sun C.

This reduces the number of moving parts in ABI compatibility checks.
Additionally, it also allows to use OpenSSL in FIPS mode while still
using md5 for non-security tasks.

Now GCC 6 and onwards will use -Wno-unused-parameter.

Now we always set NGX_CC_NAME to "msvc", and additionally test compiler
version as reported by "cl" in auto/cc/msvc (the same version is also
available via the _MSC_VER define). In particular, this approach allows
to properly check for C99 variadic macros support, which previously was
not used with MSVC versions not explicitly recognized.
Now unneeded wildcards in NGX_CC_NAME tests for msvc removed accordingly,
as well as unused wildcards for owc and icc.

This reduces the size of headers by over 30% on average.
Based on the patch by Vlad Krasnov:

The auto/module script is extended to understand ngx_module_link=DYNAMIC.
When set, it links the module as a shared object rather than statically
into nginx binary. The module can later be loaded using the "load_module"
directive.
New auto/module parameter ngx_module_order allows to define module loading
order in complex cases. By default the order is set based on ngx_module_type.
3rd party modules can be compiled dynamically using the --add-dynamic-module
configure option, which will preset ngx_module_link to "DYNAMIC" before
calling the module config script.
Win32 support is rudimentary, and only works when using MinGW gcc (which
is able to handle exports/imports automatically).
In collaboration with Ruslan Ermilov.

Previous workaround to avoid warnings on OS X due to deprecated system
OpenSSL library (introduced in a3870ea96ccd) no longer works, as
the MAC_OS_X_VERSION_MIN_REQUIRED macro is ignored on OS X 10.9
if a compiler used supports __attribute__(availability).
|
|
Notably, "-debug" was omitted, resulting in an executable without debug
symbols.
|
|
Warnings about GetVersionEx() deprecation silenced. Precompiled object
linked in.
|
|
Modern clang versions seem to no longer produce warnings for
system headers on Linux (at least clang 3.3 works), hence the
change. For older versions --with-cc-opt="-Wno-error" can be
used as a workaround.
|

Precompiled headers are disabled as they lead to internal compiler errors
with long configure lines. Couple of false positive warnings silenced.
Various win32 typedefs are adjusted to work with Open Watcom C 1.9 headers.
With this patch, it's now again possible to compile nginx using owc386,
with options we normally compile on win32 minus ipv6 and ssl.
|
|
Previously, if configured with --with-cc="clang -g", the autotest.dSYM
directories were left unremoved.

The -Werror is commented out to not break builds on Linux.

It is commented out to not break builds with 3rd party modules.

New versions of icc confuse auto/cc/name due to introduced handling
of a "icc -v":

in order to simplify support of its future versions.

At least Sun Studio 12 has problems with bit-fields exposed by nginx code
(caught by test suite). They seems to be fixed in Sun Studio 12.1. As a
workaround use "-fast -xalias_level=any" for older versions, it resolves
the problem.
