## Check if --with-regex was given.  ##

# 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.
