And here come the unit tests for pthread_sigmask. One test in single-threaded
situation (not linked with -lpthread), one test in a multi-threaded program.
I let you guess on how many platforms the tests fail...
2011-07-08 Bruno Haible <address@hidden>
Tests for module 'pthread_sigmask'.
* modules/pthread_sigmask-tests: New file.
* tests/test-pthread_sigmask1.c: New file, based on
tests/test-sigprocmask.c.
* tests/test-pthread_sigmask2.c: New file.
======================== modules/pthread_sigmask-tests ========================
