I just downloaded cygwin 1.5.24-2 (just a couple of hours ago) and compiled the following program with "gcc -ansi fred.c" (NOTE the "-ansi" keyword):
#define pid_t fred was here #include <stdio.h> int main(void) { printf("hello, world\n"); return (0); } And got the following result: In file included from /usr/include/stdio.h:46, from fred.c:3: /usr/include/sys/types.h:180: error: parse error before "was" In file included from /usr/include/sys/types.h:373, from /usr/include/stdio.h:46, from fred.c:3: /usr/include/cygwin/types.h:146: error: parse error before "fred" ie it is hitting a typedef for pid_t This is the compiler version: gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) Copyright (C) 2004 Free Software Foundation, Inc.

Is "-ansi" not the correct thing to do to get pure ANSI C89 headers? BFN.
