It appears that the shell commmands for building a library are specified via
TSystem::SetMakeSharedLib and TSystem::SetMakeExe(..), you can look at the
current settings with the related GetXXX, i.e. gSystem->GetMakeSharedLib() ,
etc. See base/src/TSystem.cxx.
In my personal installation it appears by default to use "g++" (with no
absolute path) so in such a case you can probably just put your alternate
compiler in your path before the one you would normally use. You'll find,
however, that the version used at SLAC by BaBar (for example) is
using "g++-2.95.3" to be consistent with the compiler used for the rest of
the software. There are however undoubtedly issues related to mixing compiler
versions so you may have to be more specific about what you want to do.
