Compilation on Windows 10 64 bit

Dear Developers,
I'm trying to compile the library with fortran bindings using the cygwin64 toolchain.
Making make install, I got the following error:

(cd fortran && make) || exit 1
make[1]: Entering directory '/home/sgroi/apps/source/libint-v2.6.0-cp2k-lmax-4/fortran'
g++ -E -DHAVE_CONFIG_H -D__COMPILING_LIBINT2=1 -D__COMPILING_LIBINT2=1 -I../include -I..//include -I/usr/include -O3 ../include/libint2.h > ../include/libint2.h.i

make[1]: Leaving directory '/home/sgroi/apps/source/libint-v2.6.0-cp2k-lmax-4/fortran'
make: *** [Makefile:38: fortran] Error 1

I configured with: ./configure --with-gnu-ld --with-cxx-optflags=-O3 --with-cxx=g++ --enable-fortran=yes --with-fc=gfortran

Thanks a lot for the help.
Best regards,
Mauro Sgroi.

sorry for the late reply, this is actually not an issue with Windows or libint, but rather a regression in gcc-10, see also https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95889
