I'm getting the error below building wm/awesome on DragonFly 1.10.1.

It's complaining about some types in /usr/include/regex.h, which I think
means there's another header file somewhere that has those things defined
which isn't getting included.

Based on my limited knowledge, it could be that DragonFly is defining
those types in a separate file, and those values (at least on Linux or
other BSDs) are normally included in another file.  If I'm right, someone
can hopefully point out the proper include.

Error follows, for completeness:
