Gcc Error

[Thomas Dineen <tdineen@ix.netcom.com>]

Gentle People:

     When Building a rather large project gcc produces the following error:
"Out of memory for code representation:" See the details below.

What is the best or simplest way to fix this?

1) Will using 64 bit via the -m64 flag fix this?
or
2) I am currently building the project with single gcc call. (The slow way)
Due to some legacy issues with GTK/Cairo and extern variables one big build
seems to work. Would it be better to compile each .C File to a .O file 
and then
link (Faster way).

3) I am using an older gcc 3.4.6 on Solaris 10. Would a simple update to 
a newer
version solve the out of memory problem shown above. (Separate from the -m64
issue shown below)?
