civodul pushed a commit to branch master
in repository guix.

commit e9b7adde0ddc8489e63d843a8bd8b76dc6bd6ead
Author: Ludovic Court├Ęs <ludo@gnu.org>
AuthorDate: Tue Mar 1 10:23:13 2022 +0100

    gnu: guile@3.0.8: Get correct type sizes when cross-compiling.
    
    This works around <https://issues.guix.gnu.org/54198>, whereby
    cross-compilation from (say) x86_64-linux to i586-pc-gnu would produce a
    broken Guile that crashes at startup.
    
    * gnu/packages/patches/guile-cross-compilation.patch: New file.
    * gnu/local.mk (dist_patch_DATA): Add it.
    * gnu/packages/guile.scm (guile-3.0-latest)[source]: Use it.

+When cross-compiling, get type sizes of the host system, not the build system.
+
+This is Guile commit 24b30130ca75653bdbacea84ce0443608379d630, which
+fixes <https://issues.guix.gnu.org/54198>, with one difference: it uses
+8 instead of SIZEOF_INTMAX_T, such that we do not need to modify
+'configure.ac' to check for the size of 'intmax_t' and to run 'autoreconf'
+(libguile/numbers.c expects SCM_SIZEOF_INTMAX_T = 8).
