Subject:	djgpp 1.12 is on it's way

Well, after a week of network and modem difficutlies, 1.12 is finally
on it's way to simtel.  Official announcements will be posted to
simtel's usual mailing lists and newsgroups when it's finally
available in oak.oakland.edu:pub/msdos/djgpp.  Attached is new112.doc.

The only remaining known bug is one that came up after I started the
transfer sequence, which has to do with movedata() not masking off the
high four bits of _go32_info_block.linear_address_of_transfer_buffer
like dosmem*() does.  Oh well, you can't win them all.

1.12 happened mostly to reduce the overhead of maintaining and
installing 1.11's maintainence releases.  There is new functionality
as well.

Note that the new command-line quote handler will not be used with
programs using old stubs.  Your programs will still work the way they
used to work.  The new stub passes an extra parameter to go32 that
allows go32 to properly parse the command line in a more unix-like
way.  To switch to a new stub, use "exe2coff prog.exe" and then
"coff2exe prog".

Also note that the keepmem value in the stubinfo structure is now used
by go32 to reduce paging when spawning when not in DPMI mode.  Gcc and
make are set to not swap when they use less than 1M of extended or
expanded memory.  DOS memory is still swapped out, but this is usually
only around 24K.

djgpp 1.12 no longer contains Info-Zip's sources, since Info-Zip
distributes djgpp binaries of their programs already.

-- About Globbing --

Command line expansion now understand wildcards like */*.[ch].  See
the libc.a info page of fnmatch() for details.  Also, quoting has been
fixed but if your application uses a pre-1.12 stub, you won't see the
fixes.

-- About Environments --

If you set the DJGPP environment variable to point to a file, that
file will be used to load the environment.  See the file
docs/djgpp/readme.doc for more details.

-- About documentation --

The texinfo files in docs/djgpp have been restructured to be more
maintainable.  Please be sure to include documentation changes for any
library changes you submit for djgpp.  The files you should change are
the two-letter files in the library-named subdirectory off docs/djgpp.
Use the file that matches the first two characters of the function
name (stripping any leading underscores).  The @node lines are
reformatted by the scanner; you should type in the node name and the
functional group name.  Entries are automatically sorted
alphabetically.
