# Build the config.h file, using the buildconfig program, first ensuring that
# it exists.
# 22-May-1996: remove the use of the "-a" flag for /bin/sh because it is not
# implemented in the FreeBSD shell. Sigh.
# 12-Mar-1997: add s/#.*$// to the sed script to allow for comments on the
# ends of settings - someone got caught.
# 18-Apr-1997: put the tab character into a variable to stop it getting
# lost by accident (which has happened a couple of times).
# 19-Jan-1998: indented settings in the makefile weren't being handled
# correctly; added [$st]* before \\([A-Z] in the pattern, to ignore leading
# space. Oddly, the pattern previously read ^\([A-Z which didn't seem to
# cause a problem (but did when the new bit was put in).
# 04-May-2005: if $1 is set, copy it into $MAKE, and then use $MAKE, if set,
# instead of "make" so that if gmake is used, it is used consistently.
if [ "$1" != "" ] ; then MAKE=$1 ; fi
if [ "$MAKE" = "" ] ; then MAKE=make ; fi

# BEWARE: tab characters needed in the following sed command. They have had
# a nasty tendency to get lost in the past, causing a problem if a tab has
# actually been present in makefile. Use a variable to hold a space and a
# tab to keep the tab in one place. This makes the sed option horrendous to
# read, but the whole script is safer.
