Hi Ralf, and thanks for the report.  And isn't autotest output lovely for
debugging?

I'll have to look closer at 52 - all the gnulib patches have been applied
now, so it may just be an honest difference in opinion between cygwin and
linux on how stdio.h handles a closed fd 0 in error output.  If that is
the case, then I will need to patch the testsuite to be more tolerant.

For 59-62, I think I've seen that failure pattern in one of my own trees.
 A while ago, I moved the build location of modtest.la from modules to
tests for the sake of 'make installcheck', but that means that even 'make
distclean' won't remove a bogus modules/modtest.la.  During 'make check',
libtool finds modules/modtest.la on the path first (thanks to the tests/m4
wrapper), but it is broken, hence the error.  Try 'find
~/download/cvs/m4/build -name modtest.la -delete' and see if that clears
up the error.
