Trouble compiling nginx on AIX 5.3

[Earle Ake]

I am having issues getting nginx v1.2.6 compiled on AIX 5.3.  This is
the first time I have tried on AIX.  I am using the configure line:

./configure --without-http_rewrite_module --without-http_gzip_module
--with-http_ssl_module --with-zlib=/usr/lib/

It gets so far in compiling then stops at this error:

        gcc -c -pipe  -O -W -Wall -Wpointer-arith
-Wno-unused-parameter -Werror -g  -I src/core  -I src/event  -I
src/event/modules  -I src/os/unix  -I objs  -o

Stop.

I also tried V1.2.4 and got the same results but a slightly different
line number.  Any help?
