Hi Misha.

This all seems okay.

That works for me. I'm not sure how Magnus envisaged this being used 
though. An alternative would be:

   ifeq ($(OPENJDK_TARGET_OS), windows)
       BUILD_HOTSPOT_JTREG_EXECUTABLES_CFLAGS_exeFPRegs := -MT
+     BUILD_HOTSPOT_JTREG_EXCLUDE += exesigtest.c
+ else
+     BUILD_HOTSPOT_JTREG_EXECUTABLES_LIBS_exesigtest := -ljvm
   endif

but I think your version is more future-proof.

Thanks,
David
