There's probably some scope for doing that, but not in all cases, as 
some files are built multiple times with different compilers and/or flags.

e.g. path.cc is built with a cygwin compiler and -DFSTAB as part of 
mount, with a MinGW compiler as part of cygcheck, and with a MinGW 
compiler and -DTESTSUITE as part of path-testsuite.
