Hello to everyone.

I have downloaded from CVS (cvs -d:ext:anoncvs@savannah.gnu.org:/cvsroot/gcc -qz9 checkout -P gcc wwwdocs) the latest (complete) GCC (version 4.1 if I am not mistaken) sources (gcc, ~230MB; wwwdocs, ~14MB). Now, I want to build it and I would like some tips/ advices since it is the first time I am attempting to do this (I have already a prior version of GCC -3.3.5-, bundled with the distro). Specifically:

Regarding the preresquities, it states that it needs an ISO C90 Compiler. I am wondering where I can find such a compatible compiler. All the other preresquities are met by my system (or I hope so :-P)

At the building instructions, it states that objdir should be different than the source dir. Than means I should create a new folder on my home folder and invoke make from there?

Also, it states that various errors will probably appear while building. Are there any specific errors that I should (or should not) pay any specific attention to?

Will it there be any problem with the existing rpm-based installation of GCC?

Last, I would like to ask something considering any future packages I may install. It is possible that some rpm package I may install in the future might require gcc. Will it there be a problem, 'cause it is built from source??

Any other advice, or something more that I need to know would be welcome.

Thnx in advance.
