It's not the only case.  It's perhaps the only case in your subset, 
maybe even the only case for modules in libposix (dunno if regex is in 
libposix, actually), but not in general.  Most headers are not 
replacement headers.  You can safely add the CPPFLAGS, it's not a hack 
and it's the way gnulib should be usde.

With pleasure. :)
