gcc-3, g++-3, g77-3 for cygwin

[LMH]

Hello,

I am in the middle of the complicated process of trying to restore gcc3 
to my cygwin install, while still keeping gcc 4.7. Up to a few months 
ago, gcc3 and gcc4 were installed alongside each other in cygwin. The 
gcc link pointed to gcc4 and if I wanted gcc3, I used gcc-3 when 
indicating the compiler in make. This worked well, but when cygwin 
upgraded to 4.7, the package manager removed all gcc3 files and binaries 
from my install, instead of just upgrading gcc4 and leaving version 3 as 
it was. I still have not received an explanation as to why it was 
necessary to remove version 3, as opposed to leaving it the way it was 
with both compilers available.

At any rate, I am looking into building gcc3 from src so I will still 
have it available. In the past, I was using gcc 3.4. I have found the 
src for 3.4.4-3.4.6 at ftp://gd.tuwien.ac.at/. I am looking for some 
notes for how to build this for cygwin.

I did at one point manage to get 3.4.4 installed on my current cygwin by 
using the cygwin time machine, but when I tried to compile with it I got 
an error.

#error ERROR: You must use a GNU Compiler version >= 3.4.5.

I think this was from a header file _mingw.h. For this reason, should I 
make sure I build 3.4.5 or 3.4.6 and stay away from 3.4.4? I guess I'm 
asking if 3.4.5 or 3.4.6 would be more compatible with my 4.7 gcc 
installation.

Assistance would b greatly appreciated.
