I followed the latest instructions and the initial build went smoothly, though gnatdll was not built. I fixed that up with a separate, manual, "make gnattools". Now I can produce the hello world example and make a DLL via gnatdll. One last question - I still see msvcrt.dll in ldd output of my executable and DLL. I even tried making a new specs file with -lmsvcrt replaced my -lucrt, but that DLL still shows up in the ldd output. I suppose I am missing something here - is this or is this not expected behavior? We would like to not have msvcrt.dll in the mix as this has proven to cause lots and lots of pain in the past (allocated in one DLL, free in another, for instance). Thanks for all the help thus far.
