That should have been -pg, not -gp.

How did those "-gstabs+ -W -Wall" got into this this command?  Did you
edit your specs file or something?

It will never work to compile library functions with "-ansi -pedantic",
so it's no use trying.  If you want a paranoiac set of compiler
switches that does work, use the ones in the file gcc.opt from
djlsr203.zip (but drop the -nostdinc one, for obvious reasons).

Expected, because you should use -gp.

Expected, because you shouldn't use -ansi -pedantic (ANSI C doesn't
know about `inline').

It doesn't matter, any -gSOMETHING switch will do for profiling.

Yes, of course: ld.exe is a one-pass linker.

Don't give up, help is on its way ;-)
