I noticed this when running the new gendocs.sh on the Autoconf tree on cygwin; when I tried the same process on Linux, there was no problem. Since cygwin enforces a smaller cap on number of open fd, I suspect that makeinfo might have an fd leak, although I have not investigated further at this point. I reproduced this by using 'gmake web-manual' using the latest autoconf.git.
