New GCC available for testing (TRY 3) -- fixes -mno-cygwin pr oblem

Title: RE: New GCC available for testing (TRY 3) -- fixes -mno-cygwin pr oblem





When I upgraded earlier this week I used setup.exe (not the 1.48 version) and it apparently didn't unpack gcc correctly.  I was missing at least /usr/lib/gcc-lib, maybe more although the tar file was downloaded just fine.  Running the same setup.exe and explicitly installing gcc worked.  Thanks.  Turned out it also didn't unpack a few other things completely... (weird)... so I've fixed all that too as best I can tell.  I still can't get AC_CYGWIN to work in configure but the compile of my test case works fine.
