65 |
Hmm, actually, _REENTRANT *is* the wrong flag for threads. |
66 |
But, unfortunately, the *thread* thing #define errno *errnolocation() |
67 |
is bound to this flag by POSIX (mas o menos). |
68 |
You need the reentrant functions in every stupid single threaded signal handler. |
69 |
Therefore, it's a pretty poor idea of Solaris (albeit very POSIX compliant) |
70 |
to not define them unless _REENTRANT. |
