* Made error messages print out what directory failed chdir()
* Put quotes around search arguments to grep
* Use `egrep' instead of `grep -e' because they are equivalent but `grep' does
  not have the `-e' option on Sparc/Solaris
* Added `--enable-jit' to the ./configure command because both X86 and Sparc
  have JITs and we want them to be tested
* Fixed the regular expressions parsing the changes in CVS which were causing
  the script to die
