Hmm, this seemed to bounce...

Hi,

Attached are two files, stpncpy.c and makefile.
Both are intended to be put in the directory
tests\libc\compat\string, with stpncpy.c being
an addition and makefile being a replacement.
The makefile adds a line to include stpncpy.c
in the tests, while stpncpy.c is a test file
for the stpncpy function.  (I basically copied
it out of tester.c found in the GNU sources.)

Thanks.

Thanks.

A test program would be nice, though...
