This case is no problem at all: to quote from the README file:

    But if I change compiler options like -D_REENTRANT_ or -O2 or -g ?
    That's actually an easy point. compilercache puts the commandline
    options also into the cache. If you use other commandline options,
    recompilation will take place.

So different command line options (e.g. to choose the
compiler version) will lead to different cache files.  The
only problem is the case, when the same command line, say
"gcc -c test.c", suddenly should lead to different output, because
the default behaviour of gcc changed.
