Hello

I'm new to ICE and I wanted to build for Solaris using gnu compilers
but I found out that by default it uses Sun C++ 5.4.

So I have created some patches for GCC 3.4.1. Is there any chance of
seeing them folded into the official sources so I don't have to this
patching again next time?

I edited the master makefiles to allow a general way to optionally
use gnu compilers for any platform not just Solaris.

To select gnu compilers you set a new variable `USE_GCC' in Make.rules
that will cause it to select:

Make.rules.<UNAME>-gcc

I implemented a SunOS version `Make.rules.SunOS-gcc' for my purposes.

Patches are attached.


Thanks,
