failed to compile gcc-2.95.2

[Olrik Just <Just fokus gmd de>]

Hi all,


Due to a requirement of a software project, i need to compile the gcc-2.95.2 under RH7.0.
But the compilation failed.

It does not fail during the first stage (using gcc-2.96 of RH7.0),
it fails when compile gcc with the first/second stage compiler with an error
on/with the include files/types.

I changed the used compiler from the gcc-2.96 to egcs (gcc-2.91).
The compilation aborts too.


Remarks:
- I applied the egcs-libio.patch posted in this mailing list.
- glibc-2.94-3 updated


Here the command lines i used to compile the compiler.
