Hi.
I just did a fresh install of the 64 bit cygwin on a new Windows 10
computer. I am trying to build gawk from git master and getting
failures. It looks like something is being miscompiled in the NODE
union. Compiler is GCC 5.4. I have no problems with this compiler
on Ubuntu 16 or with GCC 4.9 on an older 64 bit cygwin.
Also, when running configure, there are a lot of errors about not
being able to remove conftest.exe, device or resource busy, which I do
not get on the older Cygwin.
Repeat by
git clone http://git.savannah.gnu.org/r/gawk.git
cd gawk
./bootstrap.sh && ./configure && make -j && make check
Watch several of the checks crash and burn
Interestingly enough, compilation of the released gawk-4.1.4 tarball
goes off without a hitch; the test suite runs to completion with
no problems.
Please help.
Thanks!
Arnold

No, I don't. I just ran the exact sequence as above on a x86_64 Windows
10 machine with Cygwin 2.8.0 and gcc 5.4.0 and "ALL TESTS PASSED".
Sure you're not suffering a BLODA problem?

For me this has always been due to the AV having the conftest.exe open.
I always use an external USB drive for all of my development and state
to the AV to not check the drive letter.

Well, here is some more info. After installing MPFR and GMP development
packages and rerunning configure, the compile and tests run with no
problems.
Really strange. I note that my compilation of gawk 4.1.4 where
things went OK was _without_ the MPFR and GMP development packages.
Another interesting data point. On GCC 4.9.0, if I compile without
MPFR, I get the same set of failures.
Thanks!
Arnold
