__issignaling is a recent glibc addition, not a standard C library function; you can't assume it's available in a test without using a suitable effective-target that tests for whether it's available. I believe linking with -lm is the default in the testsuite so shouldn't need specifying explicitly. -- Joseph S. Myers jos...@codesourcery.com
