Problem: F<tools/dev/cc_flags.pl> prints the input file name before
compilation. Visual C++ does this too, yielding output like this.

...
src\exec.c
exec.c
src\exec_cpu.c
exec_cpu.c
src\exec_save.c
exec_save.c
...

Possible Solution: Check if the compiler is Visual C++ and print only
the path to the directory if so. The new output looks like this.

...
src\exec.c
src\exec_cpu.c
src\exec_save.c
...

Note that the directory path C<src\> is printed by the script, the file
name by the VC compiler.
