configure: error: sizes of long and void* are not identical

[Andrey Sukhorukov]

Dear Developers,

I get the following error when trying to compile guile 1.9.13 for
64-bit Windows system using http://mingw-w64.sourceforge.net/
compiler:

"configure: error: sizes of long and void* are not identical"

The corresponding sizes determined by configure script are:
"checking size of long... 4"
"checking size of void *... 8"

The configure options are
LDFLAGS="-L/usr/lib -m64" CFLAGS="-I/usr/include -m64" ./configure
--host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 --prefix=/usr

Please let me know if additional information/testing is needed to fix
this problem. Thank you.

Best regards,

Andrey
