Hi Joel,

I take it you have changed sim/erc32/configure.ac (or another file that 
goes in making sim/erc32/configure) and you want to re-generate 
sim/erc32/configure?  In that case, you just need to go in the sim/erc32 
and run "autoconf" ("autoconf -f" may sometimes be useful if autoconf 
doesn't realize some things have changed).

You should use the same version of autoconf as the version that 
generated the current configure.  As you can see in the header, this is 
autoconf 2.69:

   # Generated by GNU Autoconf 2.69.

Some Linux distributions have local patches to autoconf, which results 
in spurious diffs when re-generating configure.  If that happens, try to 
build and use autoconf from upstream.

Thanks,

Simon
