Subject: [PATCH 2/2] gnu: cross-base: mingw: Use winpthreads by default.
Date: Wed, 14 May 2025 08:45:22 +0200

Using a version of mingw-64 with winpthreads, packages that support posix
threads, such as Guile, can be (cross-)built for MinGW with thread support.

Also, since gcc-13, a MinGW (cross-)compiler provides g++ with std::mutex when
built with a version of mingw-w64 that has winpthreads enabled.

* gnu/packages/cross-base.scm (cross-gcc-toolchain/implementation):
Add #:with-winpthreads? parameter, defaulting to #t.  Pass it...
(cross-libc*): ...to new #:with-winpthreads? parameter here, defaulting to #t.
Pass it to make-mingw-w64 for winpthread support.
