commit ca30c090c37b4fcb6ced9e51748937223401d2f7

automatically detect GCC vs VC and set VC ver number on Win32
This fixes a bug, if you use gmake, without a GCC in PATH (but you do have
a VC in PATH) GNUMakefile is unusable because target info fatally errors.
I usually keep a strawberry perl's /c/bin dir in PATH for dmake and gmake
on my VC builds, but in 1 build config, I installed gmake to my C:/Windows
dir and did not have SP's /c/bin dir in my PATH, so GNUMakefile was broken
in that case. This patch fixes the bug.
-move the gcc -dumpversion shell outs to the GCC only section in both mkfs
dont run gcc -dumpversion on a VC build
-dont have a default CCTYPE anymore, autodetect it, if user supplies CCTYPE
explicitly on cmd line to make tool, then dont do autodetection (its
faster by 50-100ms to manually specify CCTYPE not call gcc.exe and cl.exe
with the auto detect code), "FREE" detection is unimplemented but seems
to make no difference with VC except for an old rare "free" VC 2003
I personally use a paid VC 2003.
-silence console messages and warnings from a missing gcc.exe causing
"gcc -dumpmachine" to warn or fatally error, gmake doesn't care about
exit code, dmake does
-on dmake, use := instead of *= or =, otherwise the long for loop shell
line runs dozens of times (multiple eval problem)
-on dmake, since GCCBIN macro doesn't exist and dmake mfk is "simpler"
than gmake just call gcc.exe always and not a prefixed version of GCC for
the GCCTARGET macro, it isn't used outside the autodetection code anyways
and if a user neglected to specify CCTYPE it is assumed they neglected to
specify GCCCROSS too
