+ * fixed bug 190: RUN-PROGRAM should now work properly, respecting
+ signals received, on the PowerPC platforms (both Linux and
+ Darwin). (thanks to Pierre Mai for pointing out the location of
+ the error)
+ * several fixes on OS X: The system now builds and runs cleanly on
+ Panther (10.3), and works around sigreturn bug (no more SIGFPEs).
