I intended 017_shm.pl to be skipped on Windows builds; it's not apparent
to me that that script tests anything useful when we're not using SysV
shared memory.

I don't quite understand what the msys2 platform might be doing with
these IPC modules. Do they actually do anything, or just fail at
runtime? If the latter, maybe we can add something to the eval{}
block to check for present-but-doesnt-work?
