Thanks.

I myself have not tested profiling. Seems that after all changes in djgpp
related configuration files not only by me definition of LIB_SPEC has
disappeared from djgpp.h. Perhaps I should put it back

It's gcc-2.95 and I don't see any special reason to change it. For
egcs-1.1.X I had to modify version string as 2 dots there are not
acceptable. With gcc-2.95 there are no such problems so I think there is 
no need to change anything. Also in Linux I'm getting directory 
/usr/lib/gcc-lib/i586-pc-linux-gnu/gcc-2.95/

I have not looked at these things much. Maybe it's best to ask related
questions in egcs mailing list (egcs AT egcs DOT cygnus DOT com). I'll see answer
also there.

Anyway I think that defaults for i[3456]86 should not be so bad.
