OFYI, I have tried to bootstrap gcc301 some days ago in a DOS session of Win95
and it fails in *exactely* the same way at *exactely* the same line of function __muldi3
of file libgcc2.c.
This is completey independent of the amount of memory I have used, *independent*
of the memory modules used and *independent* of the motherboard used. I have not tried
to investigate this in depth because it has been argumented that gcc301 is ok and
that all this difficulty is a cyrix cpu peculiarity or a cyrix / motherboard incompatibility.

Guerrero, Jaun M.
