+Subject: [PATCH] Fix configure with Clang 15 (implicit function declarations)
+
+Clang 15 makes implicit function declarations an error by default
+which leads to configure falsely thinking `pthread_setname_np` is
+not present:
+```
+checking for pthread_setname_np... no
+```
+
+This fixes that issue and the following errors:
+```
+error: call to undeclared function 'pthread_setname_np'; ISO C99 and later do
not support implicit function declarations [-Wimplicit-function-declaration]
+error: call to undeclared function 'pthread_setname_np'; ISO C99 and later do
not support implicit function declarations [-Wimplicit-function-declaration]
