Hi, This is because RTEMS does not have some of the errno's and they get turned into -1. And then the Ada compiler complains that there are multiples with -1. g-socket.adb:1902:25: warning: condition is always False g-socket.adb:1902:25: warning: (see test at line 1900) OK to commit? 2010-09-28 Joel Sherrill <joel.sherrill@oarcorp.com> * g-socket.adb: Move pragma to disable warnings in case multiple errnos are not defined by target.
