This is the warning enabled by -Wtraditional, and you get it for all
functions that have full prototypes, i.e.:
# [EMAIL PROTECTED]:/tmp/foo$ cc -Wtraditional foo.c
# foo.c: In function `foo':
# foo.c:4: warning: traditional C rejects ISO C style function definitions
# foo.c: In function `main':
# foo.c:10: warning: traditional C rejects ISO C style function definitions
# [EMAIL PROTECTED]:/tmp/foo$ cc -Wtraditional bar.c
# [EMAIL PROTECTED]:/tmp/foo$ diff -u bar.c foo.c
# --- bar.c Tue Jul 25 03:53:59 2006
# +++ foo.c Tue Jul 25 03:52:13 2006
# @@ -1,12 +1,12 @@
# #include <stdio.h>

# return 0;

Either the original GhostScript sources or the port uses -Wtraditional...
