Ah, it's a question of the *wrong* python being used :/. I somehow ended up
with both a mingw and an msys python, with the mingw python taking preference
over the msys one. The latter one does understand such paths.

Thanks!
Does that recipe get you to a build where ./configure --with-perl succeeds?
I see this here:
checking for Perl archlibexp... /usr/lib/perl5/core_perl
checking for Perl privlibexp... /usr/share/perl5/core_perl
checking for Perl useshrplib... true
checking for CFLAGS recommended by Perl... -DPERL_USE_SAFE_PUTENV
-U__STRICT_ANSI__ -D_GNU_SOURCE -march=x86-64 -mtune=generic -O2 -pipe -fwrapv
-fno-strict-aliasing -fstack-protector-strong
checking for CFLAGS to compile embedded Perl... -DPERL_USE_SAFE_PUTENV
checking for flags to link embedded Perl... no
configure: error: could not determine flags for linking embedded Perl.
This probably means that ExtUtils::Embed or ExtUtils::MakeMaker is not
installed.
If I just include perl.h from a test file with gcc using the above flags it
fails to compile:
$ echo '#include <perl.h>' > test.c
$ gcc -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -D_GNU_SOURCE -march=x86-64
-mtune=generic -O2 -pipe -fwrapv -fno-strict-aliasing -fstack-protector-strong
test.c -c -I /c/dev/msys64/usr/lib/perl5/core_perl/CORE
In file included from test.c:1:
