pkgconfig compile failure

[Trond Hasle Amundsen <t h amundsen usit uio no>]

Building pkgconfig-0.14.0 on AIX 5.1 with the IBM compiler fails with
the following error:

  "pkg.c", line 816.61: 1506-068 (S) 
  Operation between types "void*" and "int" is not allowed.

Compile command was

  CC='cc -O2 -D_POSIX_C_SOURCE -qlanglvl=ansi' ./configure; gmake

The following simple patch fixed this:

Forcing the compiler to accept the "bug" is probably not the best
solution, but at least it compiles... I'll leave it to someone more
proficient in pkgconfig to provide the correct fix :)

BTW, the HP-UX compiler (and a couple more, can't remember which) also
whined about the same problem before my "fix". Darwin (MacOS X) is
utterly broken and I won't even _try_ to make that work :/

The compiler also complained about other type mixups in different
parts of the code, but nothing too serious it seems.

Hope this helps.
