The question you're asking is about the C language, not the gcc
compiler.

I see no evidence of that. Your "make" output shows:

The error says what it means: struct sigset_t is defined twice. It
cannot be, because the compiler cannot serve two masters. That is,
there can be only one definition for each type.
Based on the directory names,
/opt/freeware/lib/gcc/powerpc-ibm-aix7.1.0.0/...
and
/usr/include/sys/time.h
it would seem that copy of sys/types.h was either installed by the Pro*C/C++ compiler, or installed for the sake of that compiler.
Perhaps the last time your application was compiled, there was only one C compiler installed on the machine. Now, it would seem there are two.
You need to decide which compiler to use, and which libraries and header files to use with it.
