You could use an executable compressor, such as UPX or DJP.

In any case, if your scrambling algorithm is easy, you can count on
someone being smart enough to unscramble it.

I don't think so, but GCC switches are notoriously
under-documented...

It strikes me that it will be easier to learn the syntax of `specs'
than to write an additional program.

However, should you decide to replace GCC, you can start with gxx.c,
the source of gxx.exe, which is in djlsr203.zip.
