+Rem WARNING WARNING WARNING: This file needs to have DOS CRLF end-of-line
+Rem format, or else stock DOS/Windows shells will refuse to run it.
+Rem
+Rem This batch file unpacks the GDB distribution while simultaneously
+Rem renaming some of the files whose names are invalid on DOS or conflict
+Rem with other file names after truncation to DOS 8+3 namespace.
+Rem
+Rem Invoke like this:
+Rem
+Rem djunpack gdb-XYZ.tar
+Rem
+Rem where XYZ is the version number. If the argument includes leading
+Rem directories, it MUST use backslashes, not forward slashes.
+Rem
+Rem The following 2 lines need to be changed with each new GDB release, to
+Rem be identical to the name of the top-level directory where the GDB
+Rem distribution unpacks itself.
+set GDBVER=gdb-5.0
+if "%GDBVER%"=="gdb-5.0" GoTo EnvOk
+Rem If their environment space is too small, re-exec with a larger one
+command.com /e:4096 /c %0 %1
+GoTo End
+:EnvOk
+if not exist %1 GoTo NoArchive
+djtar -x -p -o %GDBVER%/gdb/config/djgpp/fnchange.lst %1 > fnchange.tmp
+Rem The following uses a feature of COPY whereby it does not copy
+Rem empty files. We need that because the previous line will create
+Rem an empty fnchange.tmp even if the command failed for some reason.
+copy fnchange.tmp junk.tmp > nul
+if not exist junk.tmp GoTo NoDjTar
+del junk.tmp
+sed -e 's,^,%GDBVER%,' -e 's, *, %GDBVER%,' < fnchange.tmp > fnchange.lst
+Rem See the comment above about the reason for using COPY.
+copy fnchange.lst junk.tmp > nul
+if not exist junk.tmp GoTo NoSed
+del junk.tmp
+djtar -x -n fnchange.lst %1
+GoTo End
+:NoSed
+echo FAIL: Sed is not available.
+GoTo End
+:NoDjTar
+echo FAIL: DJTAR is not available or no fnchange.lst file in %1.
+GoTo End
+:NoArchive
+echo FAIL: the file %1 does not seem to exist.
+echo Remember that %1 cannot use forward slashes, only backslashes.
