Compilation Error AIX

I am getting this error

make -C port all

make[3]: Entering directory
`/db2/logs/downloads/postgres/postgresql-8.2.1/src/backend/port'

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline

I found this reference on the IBM web site. The article says:

"GNU C Compiler (GCC) returns an error message if you try to #include
varargs.h. Use stdarg.h instead."

Any ideas?

Thanks!
