[open-cobol-list] Open Cobol 0.33 and IBM AIX Xlc

[Gary Cowell]

Whilst trying to get OC to compile up on AIX (I have
compiled up bdb with 1.85 compatibility and gmp
already) I find two problems so far:

1) The ./configure script detects Xlc but generates
GNU compiler options which cause Xlc to choke.

If I hack the Makefiles to get around this problem, we
find the following:

$ make
        make  all-recursive
Making all in lib
Target "all" is up to date.
Making all in libcob
        source='move.c' object='libcob_la-move.lo'

This is a problem from returning a call to a function
which returns void.

This small example:

#include <stdio.h>

static void myvoid() {
        return;
}
static void thingy() {
        return myvoid();
}

int main(int argc, char *argv[]) {
        thingy();
        return 0;
}

Will compile and work (for whatever work means in for
this code!) if you use GCC. With Xlc it will refuse to
compile it.

I don't know if there are options that could be added
to Xlc to make it accept this code but the construct
looks wrong to me anyway
