$ systype

$ cc -v

$ cat hello.c
#include <stdio.h>

int main (int argc, const char *argv[]) {
        printf ("Hello, World!\n");
        int x = 0;
        return x;

$ cc -o hello hello.c

  A declaration cannot appear after an executable statement in a block.

          int x = 0;
          ^

1 error detected in the compilation of "hello.c".

Occasionally, we will resort to compiling with gcc, but the mips compiler
generally produces tighter code than gcc, so where at all possible I have to
painstakingly patch C99-isms to get the mips compiler to accept unportable
code like the above.

This is the latest OS release, with the latest compiler and C library.

Except that some of us still have to support clients that use modern free
software on IRIX.  The system doesn't cease to exist just because SGI are no
longer providing support.  And in any case that's still more than 2 years
away.
