Subject: [PATCH] libga68: Fix posixstrerror by using the errnum parameter

Instead of using the `errnum' parameter as described in the documentation
`_libga68_posixstrerror' used `_libga68_errno' to get the error
message.  Fix this by passing `errnum' to `strerror'.

ChangeLog:
        * libga68/ga68-posix.c (_libga68_posixstrerror): Use `errnum'
        to get the error string.
