= Portability Fixes =
* Give CFLAGS to linker. Needed when using pthread-based
getaddrinfo_a() fallback.
* lib/find_modules.sh: Replace split() with index()+substr().
This should make it work with older AWKs.
* <usual/endian.h>: Ignore system htoX/Xtoh defines. There
may be only subset of macros defined.
* <usual/signal.h>: Separate compat sigval from compat sigevent
* <usual/socket.h>: Include <sys/uio.h> to get iovec
* <usual/time.h>: Better function autodetection on win32
* <usual/base_win32.h>: Remove duplicate sigval/sigevent declaration
