-dnl for a while. The WITH_REGEX symbol (which should also be
-dnl documented in acconfig.h) is used to decide which of regex.h
-dnl or rx.h should be included in the application. If
-dnl `./configure --with-regex' is given (the default), the
-dnl package will use gawk's regex. If `./configure
-dnl --without-regex', a check is made to see if rx is already
-dnl installed, as with newer Linux'es. If not found, the package
-dnl will use the rx from the distribution. If found, the package
-dnl will use the system's rx which, on Linux at least, will
-dnl result in a smaller executable file.
