Yes, it would be nice to replace the old scripts with the new ones in the 
next ADMB release. I have released adcomp/adlink/admb trios for Linux GCC, 
Windows GCC, and Windows Borland. This trio is still missing for Windows 
MSVC and I'm not sure if the Linux GCC scripts will run on Mac OS as is.

The new scripts use -r to compile random effects, instead of the 
two-character -re flag described in the ADMB-RE manual. If everyone is 
happy with the single-character flags -d -r -s, the ADMB-RE manual could 
be updated when the new scripts are released as part of ADMB. By the way, 
the -s flag does not only add bound checks, but also embeds debugging 
symbols, since bound checks are mainly used while a model is being 
developed and tested. The -s binaries are considerably larger and slower.

I also used the opportunity when releasing ADMB-IDE to clean up the bin 
directory a bit, deleting all the old scripts, sed1.exe, sedcmd, sedcmd2, 
sedcmd3, and sedflex. As you can see inside 
http://admb-project.googlecode.com/files/admb-ide-345-4.zip, the new bin 
directory contains a total of 12 files,

   adcomp.bat, adlink.bat, admb.bat
   seddf1b2, seddf1b3, seddf1b4
   sedf1b2a, sedf1b2c, sedf1b2d
   sed.exe, tpl2cpp.exe, tpl2rem.exe

instead of 26 files in the current 
A similar cleanup could be done for other releases.

Finally, a couple of points regarding the examples. I suggest renaming the 
'simple' example from the ADMB-RE to 'simpler' and include it in the 
examples directory of the main distribution. Likewise, I would also vote 
for including the 'simpdll' example from the manual. This would be a lone 
file simpdll.tpl, since the data are R objects. I have used these examples 
to successfully test admb -r (all compilers) and admb -d (Windows GCC
