Return error code from tests (#137) Use new BYE-CODE to pass an error back to the shell. Use test tools for t_alloc.fth Fixes #82
Implement (MSEC) using usleep() (#125) Use Sleep() on Windows. Need platform specific code for embedded systems. Check to see is (SLEEP) is implemented. If not then use old busy loop code. Fixes #112
Make sure terminal output is unbuffered on POSIX systems (#110) Call setvbuf on terminal initialization in csrc/posix/pf_io_posix.c. At least on one platform (OpenWRT), pForth was buffering the characters while the user typed, instead of echoing them immediately; this fixes that issue. Fixes #109 Fixes #87
