According to Gas documentation, .hidden is ELF-only. So shouldn't be
used on windows.

I think the problem is in the GMP configure script. On windows, the m4
include files are supposed to include mpn/x86_64/dos64.m4, which
overrides the definition of PROTECT.
I think you need to add a pattern in config.ac around line 3710 to
recognize a native window build using msys (which is what you are doing,
iirc), here:
64|x32)
GMP_INCLUDE_MPN(x86_64/x86_64-defs.m4)
AC_DEFINE(HAVE_HOST_CPU_FAMILY_x86_64)
case $host in
*-*-darwin*)
GMP_INCLUDE_MPN(x86_64/darwin.m4) ;;
*-*-mingw* | *-*-cygwin)
GMP_INCLUDE_MPN(x86_64/dos64.m4) ;;
*-openbsd*)
GMP_DEFINE_RAW(["define(<OPENBSD>,1)"]) ;;
*-linux*)
GMP_DEFINE_RAW(["define(<LINUX>,1)"]) ;;
esac
;;
Alternatively, one could add a configure test for .hidden, similar to
other GMP_ASM_* tests defined in acinclude.m4. Or repurpose one of the
existing tests related to COFF and ELF features.
