* doc/bison.texinfo: Add DJGPP specific information about
|
||||
file name extensions used on different file systems.
|
||||
|
||||
* src/files.c (output_files): MSDOS conditional removed.
|
||||
New macro EXT_TYPE will provide at runtime the appropiate
|
||||
output file extension.
|
||||
(skeleton_find) [MSDOS]: __DJGPP__ conditional added to
|
||||
inhibit the use of DOSish code. POSIX like behaviour.
|
||||
|
||||
* src/getargs.c [AS_FILE_NAME]: __DJGPP__ conditional added.
|
||||
Check at runtime if LFN-API (case preserving) is available or not.
|
||||
Do not unconditionly convert upper case strings in lower case strings.
|
||||
|
||||
* src/system.h [MSDOS] [__GO32__]: __DJGPP__ conditional added.
|
||||
__GO32__ is obsolete and its use is deprecated.
|
||||
[MSDOS]: __DJGPP__ conditional added. Use pathconf
|
||||
to choose POSIX or DOS file extensions at run time.
|
||||
[MSDOS] [__DJGPP__]: New macro EXT_TYPE. If LFN-API is
|
||||
available, the src or header file extension (.c or .h) will be
|
||||
added to the output file name. If no LFN-API is available no src
|
||||
or header file extension will be added to the output file name.
|
||||
[MSDOS] [!__DJGPP__]: New macro EXT_TYPE. Src file and header
|
||||
file extension will never be added to the output file name.
|
||||
[!MSDOS]: New macro EXT_TYPE. Src file and header file
|
||||
extensions will always be added to the output file name.

@cindex DOS
|
||||
|
||||
On DOS/Windows 9X systems the file name extensions of the output files,
|
||||
like @file{.tab.c}, that may be used depend on the file system in use.
|
||||
The plain DOS file system has limited file name length, does not allow
|
||||
the use of a set of certain illicit characters and does not allow more
|
||||
than a single dot in the file name.
|
||||
|
||||
The DJGPP port of @code{bison} will detect at runtime if (LFN) long file name
|
||||
support is available or not. LFN support will be available in a DOS session
|
||||
under Windows 9X and successors. Windows NT 4.0 needs a special LFN driver
|
||||
(@file(ntlfn08b.zip) or later available at any simtelnet mirror in the /v2misc
|
||||
dir) for proper LFN support in a DOS session. If LFN support is available the
|
||||
DJGPP port of @code{bison} will use the standard POSIX file name extensions
|
||||
of the output files. If LFN support is not available, then the DJGPP port
|
||||
of @code{bison} will use DOS specific file name extensions.
