Debian bug #157805, from 2002, relates to SunOS 4 support:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=157805
Here is the problem that it states:
The /bin/sh that comes with SunOS 4.1.4, when it processes a "." command,
parses the whole file before doing anything else, and when it does that it
creates a separate file in /tmp for each here-document. Any reasonably
complicated configure script will contain over 128 here-documents, so
/bin/sh runs out of file descriptors. As a result, you get the above
errors, and the running of the configure script gets all messed up.
I see that there is some mention of SunOS 4 in the Autoconf
documentation, but I'm not sure that it's really supported
anymore. Is it worth my keeping this bug around anymore, or
should I close it as "SunOS 4 no longer supported"?
(Strangely, the report is marked as forwarded to
autoconf@xxxxxxx, but I can't find the forwarded version in any
autoconf mailing list archive, so there must have been a hiccup
somewhere in the email chain.)
