Insane amount of memory required during compilation

Hello,

while compiling under Win2K with g++ 3.4.5 or 4.0.2, I have noticed that my 
computer was running into swap, eventually failing to compile the binary 
scorefile-test. For the record, this computer has 1GB RAM and 1GB swap.

The only solution I found so far is either to hack the makefile or (cleaner) 
touch'ing pan/data/scorefile-test.exe

Only gcc 3.4.5 is an official mingw release. The 4.0.2 has been obtained 
through cross-compilation and may not provide the level of functionality 
expected from an official mingw release.

However, being 2 different development branches, I thought the problem was 
significant enough to be reported on this mailing list. Whether the solution 
is an use of gcc4 visibility, a reduction in template nesting or anything 
else, I'm also wondering why it has never been noticed/reported before.

Best regards,
Christophe GISQUET
