Cygwin and Solaris host-compile libroot's glibc regex sources into the keymap tool - for that we need a matching header.
Why Cygwin chose that route in the first place, I don't know. Probably because no fully GNU-compatible regex.h is available on the host?
For instance, there's no single RE_* macro in OpenSolaris's regex.h header:
