AIX compile errors ?? libcrypt HELP!!

I am trying to compile an app (compiles on *BSD, Linux) but for some
reason I cant get it to compile on AIX 4.3.3.3. It seems not to like the
libcrypt ??

using:
gcc version 2.95.2 19991024 (release)
PostgreSQL 7.02
GNU Make version 3.79.1
ld ??
Flags: -I/usr/include/pgsql/ -lrts -lcrypt -L/usr/lib/psql/ -static
-lecpg -lpq -lm

gr_server.c:184: warning: passing arg 3 of `naccept' from incompatible
pointer type
ld: 0711-224 WARNING: Duplicate symbol: .connect
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more

any help would be great !!
