XXX
C<cygwin> builds may fail during testing due to a conflict between the
load addresses of F<cygperl5_41_6.dll> and
F<olib/auto/I18N/Langinfo/Langinfo.dll>. This will also be visible
for anything that attempts to fork() with C<I18N::LangInfo> loaded.

This is known to fail for builds with options that increase the size
of the binary, such as C<-DDEBUGGING>, C<-Doptimize="-O0 -g"> or
C<-Doptimize="-O2 -g -march=x86-64-v2">.

This can be avoided by building perl with
C<-Astatic_ext=I18N/Langinfo>.

The base addresses are generated by the linker based on the names of
the DLLs, so this is expected to clear up for 5.41.7.
