C TAP Harness 1.5

This is a relatively minor release with a couple of bug fixes to bring this package in sync with other work.

The ok_program function in the shell TAP library now only removes bits from error messages after the second colon instead of the first. This feature allows easier testing of programs whose error messages include the system error, but the previous version was cutting off too much since the program name followed by a colon generally starts error messages.

I've also now added several new GCC warning options and runtests.c will now compile without warnings with -Wswitch-enum.

You can get the latest version from the C TAP Harness distribution page.
