Change sanity checks on compiler versions

On all three basic OS's, have a MIN_CC_VERSION and a PREFERRED_CC_RELEASE.
e.g.

Def-solaris.gmk
  MIN_CC_VERSION=5.5
  PREFERRED_CC_RELEASE="cc: Sun C 5.5 Patch 112761-06 2004/01/13"
  ACTUAL_CC_VERSION="$(shell $(CC) -V 2>&1 | $(HEAD) -1 | $(CUT) -f4)"
  ACTUAL_CC_RELEASE="$(shell $(CC) -V 2>&1 | $(HEAD) -1)"

Defs-linux.gmk (different on each Linux X86, AMD64, IA64)
  MIN_CC_VERSION=3.2
  PREFERRED_CC_RELEASE="cc (GCC) 3.2.1-7a (J2SE release)"
  ACTUAL_CC_VERSION="$(shell $(CC) --version 2>&1 | $(HEAD) -1 | $(CUT) -f3 | $(CUT) -d- -f1)"
  ACTUAL_CC_RELEASE="$(shell $(CC) --version 2>&1 | $(HEAD) -1)"

Defs-windows.gmk
  MIN_CC_VERSION=6.0
  PREFERRED_CC_RELEASE="Visual C++ 6.0 Professional + VC6-SP 3"
  ACTUAL_CC_VERSION="$(shell $(CC) 2>&1 | $(HEAD) -1 | $(CUT) -f3)"
  ACTUAL_CC_RELEASE="$(shell $(CC) 2>&1 | $(HEAD) -1)

Sanity.gmk
  if [ "$(PREFERRED_CC_RELEASE)" != "$(ACTUAL_CC_RELEASE)" ] ; then
    warning
  fi
  if [ $(MIN_CC_VERSION) less than $(ACTUAL_CC_VERSION) ...
    error
  fi


Or something like that...
