Previously bindgen was picking the 'constified_enum'. E.g it would turn
the luw_srb_flags_t enum
typedef enum {
LUW_SRB_NONE = 0x00,
LUW_SRB_APPEND = 0x01,
LUW_SRB_ALLOC = 0x02,
LUW_SRB_FULL_SIZE = 0x04,
LUW_SRB_FLAGS_ALL = (LUW_SRB_NONE|LUW_SRB_APPEND|LUW_SRB_ALLOC|
LUW_SRB_FULL_SIZE)
} luw_srb_flags_t;
into
pub const luw_srb_flags_t_LUW_SRB_NONE: luw_srb_flags_t = 0;
pub const luw_srb_flags_t_LUW_SRB_APPEND: luw_srb_flags_t = 1;
pub const luw_srb_flags_t_LUW_SRB_ALLOC: luw_srb_flags_t = 2;
pub const luw_srb_flags_t_LUW_SRB_FULL_SIZE: luw_srb_flags_t = 4;
pub const luw_srb_flags_t_LUW_SRB_FLAGS_ALL: luw_srb_flags_t = 7;
But then this requires some further changes to make the names nicer
without the type prefixed.
This will only be exasperated when adding an enum containing the HTTP
status codes...
So instead, tell bindgen to use the 'rustified_enum' method which
produces this
pub enum luw_srb_flags_t {
LUW_SRB_NONE = 0,
LUW_SRB_APPEND = 1,
LUW_SRB_ALLOC = 2,
LUW_SRB_FULL_SIZE = 4,
LUW_SRB_FLAGS_ALL = 7,
}
which in theory requires no extra changes (it doesn't with the http
status codes enum), however in this specific case, because these are
actually bitflags we still need to cast them to u32 so they can be OR'd.

When I added the luw_http_hdr_get_value() function I needed to include
strings.h, unfortunately I added it to unit-wasm.h instead of
libunit-wasm.c
This then meant that we needed to point bindgen/clang, for generating
the bindings, to the wasi-sysroot for the strings.h file. I guess this
is a system dependant include or something and when we use the
wasm32-wasi target in clang it uses a paired down include search path
list, none of which have strings.h
This then had the knock on effect of requiring to inform cargo build of
the wasi-sysroot path.
Now that we put strings.h in the right place, we don't need the
wasi-sysroot when building the rust stuff.
