Hi, I just installed the new gcc-6.3.0-1 test package (thank's for that) and tried to install optimized gmp 6.1.2 on my Skylake i7-6700K:
$ uname -a
CYGWIN_NT-10.0 XXXXXXXXXXX 2.6.1(0.305/5/3) 2016-12-16 11:55 x86_64 Cygwin

Don't know why -march=broadwell, but -march=skylake doesn't work either.

I suppose it has something to do with the new compiler, since
- gcc-5.4.0 worked fine (okay, with broadwell optimizations)
- the just arrived gmp-6.1.2-1 package seemed to compile (with
gcc-5.4.0)
- everything works fine when I compile my own gcc 6.3.0 via
.bashrc:
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=/usr/local/lib
export CPATH=/usr/local/include:$CPATH
export PATH=/usr/local/bin:$PATH
tar xjvf gcc-6.3.0.tar.bz2
mkdir compile
cd compile
../gcc-6.3.0/configure --enable-languages=c,c++,objc,fortran
--with-default-libstdcxx-abi=gcc4-compatible
make -j 4
make install
and then install gmp as above
Is there something wrong with gcc-6.3.0-1?
Attached is a slightly redacted output of cygcheck -s -v -r >
cygcheck.out.

Torsten
