! Summary: bin\lcp.bat prepends Ant libraries to user's path
!
On DOS (not Linux or cygwin), ant.bat calls lcp.bat to add the ant libraries,
such as lib\parser.jar, to the CLASSPATH passed to ant. The problem is that
lcp.bat *prepends* (not appends) these libraries to the user's classpath.

+ Not being able to find the original lcp.bat used for Ant 1.2 (it looks like it
+ was deleted out of jakarta-ant/bin and moved to jakarta-ant/src/scripts, in the
+ process losing the history) I can't find any comments explaining the change.

+ according to this report, that wasn't always the case.

The reason not to do it is that it inhibits using ant with no CLASSPATH set
because it can lead to empty entries at start of CLASSPATH var. The way it
works now puts the possibly empty entries at end of CLASSPATH. Some JVMs stop
reading CLASSPATH entries at first empty entry and thus would never see any
of later entrys.
Cheers,
Pete
