+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.

+GoTo End
