Hi,
Through these two commits to config.sub
https://git.savannah.gnu.org/gitweb/?p=config.git;a=commitdiff;h=91f6a7f616b161c25ba2001861a40e662e18c4ad
https://git.savannah.gnu.org/gitweb/?p=config.git;a=commitdiff;h=28ea239c53a2d5d8800c472bc2452eaa16e37af2
the host_os values windows* (and in particular windows*-msvc*)
were introduced, to denote native Windows environments.
The commit message makes it sound like LLVM and Crablang communities will
use the windows* value, whereas GNU will continue to use mingw*. But I think
it's only a matter of time until people start to pass the option
--host=x86_64-pc-windows
to configure scripts. We should be prepared for that.
This patch does the necessary things on the Autoconf side, by accepting a
host_os of the form windows* anywhere where mingw* is accepted.
It's the same patch that I already posted in
<https://lists.gnu.org/archive/html/autoconf-patches/2023-08/msg00005.html>;
no changes are needed after the second config.git commit mentioned above.

Subject: [PATCH] Recognize the *-*-windows* config triplets introduced on
2023-06-26.
* lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Treat windows* as
equivalent to mingw*.
* lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF, _AC_FUNC_REALLOC_IF):
Likewise.
* lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_PROBE): Likewise.
