So, it seems that -Wno-underscore is broken when used with --gnu-pascal.

I can't seem to reproduce it. Did you perhaps try the options the other way around (`-Wno-underscore --gnu-pascal')? Then it would be expected behaviour since options are generally processed from left to right, and `--gnu-pascal', among other things (cf. p/gpc-options.h), sets `-Wunderscore'.

No, I thought of that. I tried various orderings and various compiler builds, all with the same result. Would somebody be so kind to try it on another platform ?

I'm not sure if this mail went through -- apparently not. Apologies if anyone gets this twice.

Ah, I see, it only happens with gcc-3.x (I had tried with 2.x).
Unfortunately, we have to patch gcc.c(!) here, since this is used to dump the `specs' file which gpc will later read and override its built-in settings which were already corrected.
Diff attached (this will go into the diffs/* file, but you can apply it manually just like a GPC diff).
Waldek, this will be an issue with GCC integration as well sometime. (I don't expect serious problems, since it's only about the ordering of arguments, except perhaps "philosophical" ones ...)

Solved. Thanks for the patch.
