Is the file gcc/doschk.c used for anything in GCC?  If not, does it belong
here?  There is, for example, another version in the src repository,
src/utils/misc/doschk/doschk.c.

It was once used to check that filenames met all the length limits
and similar rules for DOS and SysV filesystems.  It doesn't seem
that people worry much about any of that anymore, so if it's not
going to be used, no point in keeping it around.

The doschk master is doschk-1.1.tar.gz on the FSF ftp sites (on the
non-gnu side).  There is no need to keep it in any of the
repositories.

Maintainers are encouraged to use doschk on files they add to the
repository, to see any potential conflicts caused by the 8.3 file
limit.  While not an official policy to support such systems (in fact,
even djgpp's gcc is built on a system that supports long file names),
if there is little or no cost in such support there are some benefits
to doing so.

You get reports like this:

./.cvsignore - file name cannot start with dot

The following resolve to the same DOS file names:
BUILTIN-.DEF   : ./builtin-attrs.def
                 ./builtin-types.def
FLOAT-I3.H     : ./config/float-i32.h
                 ./config/float-i386.h

doschk also tests for uniqueness on old unixes with 14-character
limits, like this:

The following resolve to the same SysV file names:
FSFChangeLog.1 : ./FSFChangeLog.10
                 ./FSFChangeLog.11
unwind-dw2-fde : ./unwind-dw2-fde.c
                 ./unwind-dw2-fde.h

The following file names are too long for SysV:
cris_abi_symbo : ./config/cris/cris_abi_symbol.c
irix6-libc-com : ./config/mips/irix6-libc-compat.c
stormy16-lib2. : ./config/stormy16/stormy16-lib2.c
