I'm probably the only person building texinfo on Cygwin, but this is just a heads-up that there's a bug in gnulib/m4/threadlib.m4 that can cause mysterious crashes that are very hard to debug. The bug shows up when running 'make check' in the info subdirectory. 13 of the 85 tests fail because ginfo crashes.

The bug has been fixed in upstream gnulib (see attached). I'm not suggesting that anything needs to be done right now; the problem will be taken care of the next time you do a gnulib update.
