Hi!
Sorry to say, but we should not mirror out binaries of port of gcc-
2.95.1. I must rebuild them for target i386-pc-msdosdjgpp
The problem was that we have found very rare problem when
compiler with options -march=pentium -mcpu=pentium generates code
which doesn't run on i386. It seems to be very rare as it took half a
year to found it (my own software written in C++ is being used on 386
and never crashed due to similar things) as the same problem was with
port of egcs-1.1.2
