Hello.

Yes! Thanks to you and Hans for pointing out the problem in the problem.
;) I assumed gcc would add some stand-alone magic to the objects, but I
guess it's not suprising it needs some help from the C library to do the
timing.

This does fix the problem. I'm not quite sure how to DTRT. How about this:

Presumably we want to compile mcount.c with the same options as the rest
of the code, but without -pg and -a. So should I add a new command to
src/makefile.inc that defines a new XGCC - XGCC_NO_PG - to be used for
mcount.c? This would use a version of src/gcc.opt passed through sed to
remove -pg and -a. (Requiring sed to build library sources must be OK,
since we use sed in src/libc/crt0/makefile.)

Thanks, bye, Rich =]
