Nit: this should be

   patch-platforms__unix__plugins__PseudoTTYPlugin__openpty.h

(note the double underscore)

Dump this into a file foo, and add 
"platforms/Cross/plugins/SqueakFFIPrims/" in front of the filename, so 
you can patch < foo

I can't run an image to test this (does someone have a test image that, 
say, just spits the result of 3 + 4 to stdout? That'd be a great testing 
tool!) but certainly the build completes without error after the 
above-mentioned changes.
