Compile GRASS with cc or gcc?

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.
