Just run "gcc -c test.c" on this:

#pragma weak __pthread_initialize
extern void *memcpy (void *__restrict __dest,
       __const void *__restrict __src, int __n)
     __attribute__ ((__nothrow__)) __attribute__ ((__nonnull__ (1, 2)));
extern __typeof (memcpy) memcpy __asm__ ("" "__GI_memcpy") __attribute__
((visibility ("hidden")));

void f(void) {}

$ gcc -c test.c
test.c:5: warning: asm declaration ignored due to conflict with previous rename

With "#pragma weak __pthread_initialize" line commented out, it does not
happen.

$ gcc -v
Using built-in specs.
