The backtrace you reported before suggests that it’s stuck waiting for a
signal delivery thread mutex, right? I have no idea how this would
happen, though.

FWIW, Guile cross-builds fine to MinGW with pthread-w32 and pthread
support, but that runs none of the C code since it uses the native Guile
to compile the .scm files.

I don’t know. It’s used only in net_db.c, and only if ‘h_errno’ is
available.
Is there any harm in using it when it’s available?
Could it be that older-but-not-too-old MinGW versions required use of
‘h_errno’?
Thanks,
