The function does take into account drive names and the function is only used 
once to set the exec prefix which is what tells gcc where to look for the 
compiler.

Already fixed.

See above. I should also note that the code that only canonicalizes the paths 
stored in gcc.c that gcc needs to find the compiler, assembler, linker, 
include files, etc. Any other paths are left alone. So with a command line 
'gcc -c /dev/env/DJDIR/sourcecode.c', the given filename is not 
canonicalized.
