## --------------------------------- ## ## Check if --with-regex was given. ## ## From Franc,ois Pinard ## ## --------------------------------- ## # The idea is to distribute rx.[hc] and regex.[hc] together, for # a while. The WITH_REGEX symbol (which should also be documented # in acconfig.h) is used to decide which of regex.h or rx.h should # be included in the application. If `./configure --with-regex' is # given, the package will use the older regex. Else, a check is # made to see if rx is already installed, as with newer Linux'es. # If not found, the package will use the rx from the distribution. # If found, the package will use the system's rx which, on Linux # at least, will result in a smaller executable file.
