Thus, if any pthread function has +been provided as a macro, compiling threads.c will fail. +This breaks on musl libc, which defines pthread_equal as a macro (in +addition to providing the function, as required). + +Prevent the declarations for e.g. musl libc by refining the condition. + +The idea for this solution was borrowed from the alpine linux guys, see +http://git.alpinelinux.org/cgit/aports/tree/main/libxml2/libxml2-pthread.patch + +Signed-off-by: Michael Heimpold + +diff --git a/threads.c b/threads.c +index 8921204..78006a2 100644 +--- a/threads.c ++++ b/threads.c +@@ -47,7 +47,7 @@ + #ifdef HAVE_PTHREAD_H + + static int libxml_is_threaded = -1; +-#ifdef __GNUC__ ++#if defined(__GNUC__) && defined(__GLIBC__) + #ifdef linux + #if (__GNUC__ == 3 && __GNUC_MINOR__ >= 3) || (__GNUC__ > 3) + extern int pthread_once (pthread_once_t *__once_control, +@@ -89,7 +89,7 @@ extern int pthread_cond_signal () + __attribute((weak)); + #endif + #endif /* linux */ +-#endif /* __GNUC__ */ ++#endif /* defined(__GNUC__) && defined(__GLIBC__) */ + #endif /* HAVE_PTHREAD_H */ + + /* +-- +cgit v0.10.2 +
