Faster compilations

[Devrim Erdem]

Hi,

My huge application has many include files, many derived classes and 
several template classes. It takes a lot of time (30-40s) to compile 
some of my files on my 1GHz, 256 Mb Ram system.

Though I know that getting a faster harddrive and more RAM may help, I 
would like to ask the experts if that would really work. What takes most 
of the time during the compilation  ?

Is it possible to organize files ( other than grouping them into 
libraries ) so that they may compile faster ?

I use precompiled headers on Windows with Visual C++. Is there a similar 
technique with gcc ?

Thanks.
