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

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

I have fixed a number of related problems, and relaxed this
restriction.

However, there are still a number of problems that need fixing on a
platform where a long does not hold the longest integer type that can
fit into a pointer; you will find these when compiling numbers.c (there
is a #error that you will reach). I don't have time to fix those, but
will accept a patch.

Regards,

Andy

Thank you very much for working on this problem! I am not a
programmer, so would not be able to finish this work. Hopefully your
work would be finished by another qualified person. Then it will
become possible to port several very useful programs which are utilize
guile to mingw-64.

Best regards,

Andrey
