You can do this by building a custom version of gcc, with special option processing. Also, you can edit gcc's specs. But I wouldn't do that: it's too much trouble to solve a trivial problem. Instead I'd write a script, like this: exec /path/to/gcc -m32 $* You can override -m32 with -m64 if you need it. Andrew.
