Hi Manolis,

Thanks for the report!

Will do shortly, sorry for the delay!

Note that all three points are related, AIUI.  That is, using procedures
in make-bootstrap.scm means that the right glibc package gets chosen,
which in turn means that #4 and #5 get fixed.

Does the issue reported in the 2007 message above still holds?  What
exactly was the error when cross-compiling libgcc?  The Hurd folks may
have seen it before.

Thanks for all the uneasy & frustrating work!
