probably tcp.h require ip.h already included in AIX. I agree however
with James that code can work even if TCP_NODELAY is not present. I
noted that we have

/* under VMS we have to define TCP_NODELAY */
#elif defined(__VMS)
#define TCP_NODELAY 1
#define USE_NODELAY 1
#endif

perhaps we should define TCP_NODELAY even on AIX if not found ??

what does this command reply (after make stops) ??

$ /usr/bin/nm -B -BCpg   src/tds/.libs/libtds_objects.a
src/replacements/.libs/libreplacements.a

I think is a libtool problem with AIX and -export-symbols-regex option
(perhaps with AIX ld...). You could try to removing

-export-symbols-regex
'^(db|bcp_|tdsdump_open|tdsdbopen|.*_xact|close_commit|open_commit|.?asp
rintf).*'

part from src/dblib/Makefile.in (before configure)

not a problem, ignore it, it's only a symbol optimization.

If you could be so kind to give me a AIX account I would try to
understand this problem. It's a very longstanding issue!
