bug#37797: conf_post.h not found

[Rob Browning]

I just hit the same error.  My current suspicion is that conf_post.h
might not work right with VPATH builds yet.

Symlinking conf_post.h from the source tree into src/ in the build tree
got past this crash, but then there was different failure in the
emacs-module tests, which made me wonder if other bits of the module
tests might not support VPATH yet either.

For example, after a manual "(cd src && ln -s ../../../src/conf_post.h
.)" I see:
