This is a port of Splint 3.1.2 to MSDOS/DJGPP.
Splint is a tool for statically checking C programs for security
vulnerabilities and coding mistakes.
DJGPP specific changes.
=======================
1) The most extensive DJGPP specific changes concern the handling of the
paths. The sources offer certain rudimentary support for win32 and
OS2 compilers but this support is not good enough to allow the use of
the DJGPP syntaxes with mixed slash and backslash as directory separator
and colon and semicolon as path separator. To use the provided MSDOS and
WINDOWS support all paths given at the command line or in the supported
envirinment varaiables are transformed from the DJGPP syntax to the MSDOS
syntax and only semicolon is used as path separator.
This is done with function dosify_path that uses a bug fixed version of
the CVS version of fixpath.c.
2) The DJGPP port of Splint will honour the following MSDOS/DJGPP specific
preprocessor symbols MSDOS, __MSDOS, __MSDOS__, DJGPP, __DJGPP, __DJGPP__,
DJGPP_MINUR, __DJGPP_MINOR and __DJGPP_MINOR__ apart of all the standard
ones.
3) The configuration files .splintrc and .lclintrc have been renamed to
splint.rc and lclint.rc. No matter if LFN support is available or not
only these names will be honoured. The files are expected to be stored
in the $HOME directory or in the current working directory.
4) The environment variable LARCH_PATH can be set to define a sequence of
paths where to search for splint libraries and initialization files.
If it has not been set then the build-in default value:
.:/dev/env/DJDIR/share/splint/lib
will be used. The environment variable LCLIMPORTDIR defines the path
sequence where to search for the lcl import files. If it has not been
set then the build-in default value:
.:/dev/env/DJDIR/share/splint/imports
will be used.
Due to the way I have handled the path issue and because some functions like
snprintf are not available on DJGPP 2.03, this port can only be compiled
with DJGPP 2.04. There will be no DJGPP 2.03 version.
To compile the sources you will need LFN support. If you decide to modify
the different parsers you will need bison and flex. To avoid that the
configuration process reflects the paths of my DJGPP installation tree in
the default values for DEFAULT_LARCHPATH and DEFAULT_LCLIMPORTDIR, the
distributed sources will not be preconfigured. To run the testsuite
you will need diffutils.
As usual all the changes to the sources are documented in the djgpp/diffs
file.
Please **read** the docs stored in /gnudocs/splint-3.1-2.
Please note that I have never used Splint so I can not promisse that the
port is really perfect. I release this port because the testsuite passes
flawless.
The port consists of the two packages that have been compiled using
djdev204 and can be downloaded from ftp.delorie.com and mirrors as

Send splint specific bug reports to <splint-bug AT cs DOT virginia DOT edu>.
Send suggestions and bug reports concerning the DJGPP port to
comp.os.msdos.djgpp or <djgpp AT delorie DOT com>.
Probably every failure of splint will have it source in the changes
done during the porting, so send a bug report to me *before* you send
one to the authors/maintainers of splint.
Enjoy.
