By default, libltp tests will create temporary files in a subdirectory
of /tmp, which will (nowadays) be located relative to the test DLL (by
assuming that it is in /bin). This will evaluate to the directory
$target_builddir/winsup/tmp, which doesn't exist.
The location used for these temporary files can be explicitly controlled
by setting the TDIRECTORY env var. Arrange to set that env var to the
/cygdrive path of a tmp subdirectory of the build directory.
Unfortunately, libltp doesn't clean the temporary directory if
TDIRECTORY is set, and some tests assume they are started in a clean
directory, so we need to do that in tcl.
* cygload/cygload.cc: Move to winsup.api. Add comments from README.
* cygload/cygload.h: Move to winsup.api.
* cygload/cygload.exp: Move to winsup.api.
* Makefile.in: Remove cygload.
* winsup.api/winsup.exp: If a .exp file is detected, run it rather than using
standard compile.
* winsup.api/resethand.c (main): Use printf to print status or expect thinks
something is wrong.
variable CYGWIN_TESTSUITE_TESTS is set. Use its value as regular
expression to filter test names.
* winsup.api/ltp/symlink01.c (creat_path_max): Provide explicit
buffer to getcwd to conform to standards and avoid memory leak.
(do_chdir): Ditto.
