Compile GRASS with cc or gcc?

[amante at grouse.pnl.gov]

Fellow GrassU/GrassP's:

	I'm re-arranging the files at my site and I thought that I'd go ahead
and recompile GRASS 4.1, under it's new (and hopefully permanent) location.  
Which compiler is recommended: cc or gcc?  Which produces faster code: cc or 
gcc?  And, most importantly, which compiler (if any) does CERL endorse?  BTW, 
I'm running a Sun SPARCstation 10, SunOS 4.1.3 ...

Thanks for your help.
