Dear Maintainer, I've tried a bit solving the problem, here's a patch that builds. Mostly adding explicit includes for implicit ones that used to get away.
Though I'm not at all familiar with autoconf, so some things might not follow
best practices.
The last hunk, including pty.h, is probably placed in a wrong spot. Please let
me know, and where to put it correctly, if it's the case ;)
