Solaris 9 mkfifo("name/",mode) mistakenly creates "name".
FreeBSD 7.2 mkfifo("dangling/",mode) mistakenly creates a fifo
at the target of "dangling". Mingw lacks named pipes altogether,
but this at least avoids link failures.

This function mishandles trailing slash on some platforms:

FreeBSD 7.2, Solaris 9.
