[9fans] a jmp_buf in APE question

2013-01-06 Thread Jens Staal
Hi all. Perhaps I have been looking at completely the wrong places and perhaps I am just not grasping it at all. For a package that I want to build under APE, I need to put in the stack pointer (sp) and the program counter (pc) part of jmp_buf specific for Plan9 (since APE does not expose any s
