Can you create files in /tmp? What happens when you try the following:
$ >/tmp/foo

I would not recommend the above approach. Instead, I strongly recommend
finding the root cause to your problem. Especially, when it most likely
also relates to your second problem...

Guess where cygipc stores its files? In /tmp:
$ ls /tmp/cygipc? /tmp/MultiFile*
/tmp/MultiFileMsg /tmp/MultiFileShm /tmp/cygipc1
/tmp/MultiFileSem /tmp/cygipc0 /tmp/cygipc2
BTW, you may want to try Cygwin 1.3.1 (i.e., the latest release) or a
different snapshot. I personally tested Cygwin 1.3.1 and 20010413 and
both pass all regression tests.
