For loop in ant.bat fails in ant-1.5.1 on Windows 9x

           Summary: For loop in ant.bat fails in ant-1.5.1 on Windows 9x
           Product: Ant
           Version: 1.5.1
          Platform: PC
        OS/Version: Windows 9x
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Wrapper scripts
        AssignedTo: ant-dev@jakarta.apache.org
        ReportedBy: jbiskeborn@msn.com


I thought you might be interested in a fix for a problem I had with ant.bat in 
ant-1.5.1.
 
First, I had to change:
if exist "%ANT_HOME%" goto checkJava
to: 
if exist "%ANT_HOME%"\nul goto checkJava
 
I think this has already been reported in bug 14495.
 
Then, I found the for loop at :checkJava no longer worked.  It worked fine with 
ANT_HOME=\ant-1.5 but not ANT_HOME=\ant-1.5.1 with the .1 added.  It wasn't a 
matter of the path being too long.  It just didn't like seeing more than one 
extension.  In other words, the for loop accepted 1 followed by .5 but not 1 
followed by .5 followed by .1.
 
To get it to work I changed:
for %%i in ("%ANT_HOME%\lib\*.jar") do call "%ANT_HOME%\bin\lcp.bat" %%i
to:
rem Substitute virtual disk z: for %ANT_HOME% in for loop.
subst z: "%ANT_HOME%"
for %%i in ("z:\lib\*.jar") do call "%ANT_HOME%\bin\lcp.bat" %%I
 
After :end I added:
rem Delete virtual disk z: used above.
if exist z:\nul subst z: /d
 
This solution depends on the last drive being set to z:, which it is in Windows 
Me and probably Windows 98, and the z: drive not being used, which is probably 
the case.  There's probably a way to detect if both of these conditions are 
true.
 
I think it's important that ANT_HOME include the version number so users can 
write scripts that check the version number.
