-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,@V@,%GDBVER%,g' < 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.
