TRE just uses the regex struct to store a pointer to the real compiled
regex object.

Of course you cannot mix a system regcomp() with TRE regexec() or vice
versa.  It works as long as you use only the functions from libtre or only
from the system and don't mix and match.

Yeah.  I don't know if Windows has similar functionality.  Even if it
did, there is no system regex implementation on Windows, so for TRE
this functionality would be practically useless anyway on Windows.
