confirm the fix.


This doesn't appear to work for me with the existing expr.exe; I think you should just use new binutils but keep the static libgcc
>> linkage. The static ctors in the DLL appear to be getting run twice,
which is bad.

Take 2. I can now reproduce the problems with expr due to cyggmp-3.dll and the gcc-4 problems due to cyggmp-3.dll and cygmpfr-1.dll. I don't fully understand all of the issues - how do I check if static ctors in the DLL run twice? - so feedback is welcome.


Here is another build of gmp with CVS binutils and -shared-libgcc. I took more care and ensured that CVS binutils was used everywhere. These DLLs work with expr and gcc-4, and the gmp testsuite passes, both before and after rebasing. A build without -shared-libgcc did not work after rebasing.

I have also rebuilt mpfr in the same way. It too works for me after rebasing.

The new builds are available for testing. You really only need the new DLLs. These are in
- libgmp3-4.3.1-3.tar.bz2,
- libgmpxx4-4.3.1-3.tar.bz2
- libmpfr1-2.4.1-3.tar.bz2


My other packages - mpclib, ppl and cloog-ppl - may suffer from the same problem. A job for tomorrow.
