| 6 | # 22-May-1996: remove the use of the "-a" flag for /bin/sh because it is not | |
| 7 | # implemented in the FreeBSD shell. Sigh. | |
| 8 | ||
| 9 | # 12-Mar-1997: add s/#.*$// to the sed script to allow for comments on the | |
| 10 | # ends of settings - someone got caught. | |
| 11 | ||
| 12 | # 18-Apr-1997: put the tab character into a variable to stop it getting | |
| 13 | # lost by accident (which has happened a couple of times). | |
| 14 | ||
| 15 | # 19-Jan-1998: indented settings in the makefile weren't being handled | |
| 16 | # correctly; added [$st]* before \\([A-Z] in the pattern, to ignore leading | |
| 17 | # space. Oddly, the pattern previously read ^\([A-Z which didn't seem to | |
| 18 | # cause a problem (but did when the new bit was put in). | |

20 | # 04-May-2005: if $1 is set, copy it into $MAKE, and then use $MAKE, if set, |
| 21 | # instead of "make" so that if gmake is used, it is used consistently. | |

| 28 | # BEWARE: tab characters needed in the following sed command. They have had | |
| 29 | # a nasty tendency to get lost in the past, causing a problem if a tab has | |
| 30 | # actually been present in makefile. Use a variable to hold a space and a | |
| 31 | # tab to keep the tab in one place. This makes the sed option horrendous to | |
| 32 | # read, but the whole script is safer. | |
