I am already doing this (in a portable way) for the AutoMake mechanism. There is an "internal" option `--amtmpfile=cc123456.gpc' which passes the name of a file containing the names of the `.o' files to be linked to the `gpc' driver program.

Sounds good! Is this a way to use compiler options (like -o, -l, .o files, .c files) in the source?

If every option (except those like $R,$I,$S,$Q(?) that would be the same like BP's) would be at least 2 letters, this would avoid name clashes.

Sounds reasonable. However I like the (*$W-*) ... (*$W+*) option as a quick way to disable/enable warnings locally. (Sometimes one may want to ignore a certain warning.) To have only (*$no-warnings*) ... (*$warnings*) would be a little drawback ...

No objections from me. BP doesn't have a $W option (except Windoze stack frame for Windoze platform, but I don't care very much about that), and $W for warnings sounds general enough to justify a one-letter switch.

I'm not sure what this has got to do with it. Anyway, I think the biggest problem would be to collect all the options into one record (which might be quite hard if they're scattered among many modules now). Then, pushing and popping would reduce to storing/restoring this record to/from a (LIFO) stack.

Please look at `toplev.c', `gpc-options.h', and `gpc-decl.c' to get an overview.

Seems like a lot of work... :-(
