This declaration:
char *memcpy(char *s1, char *s2, int n);

produces these warnings:
memcpy.c:1: warning: conflicting types for built-in function `memcpy'
memcpy.c:1: warning: type mismatch with previous external decl
<built-in>:0: warning: previous external decl of `memcpy'

Should there be three warnings for the same error?
Also, it would be very nice if gcc told you what types it expects, so you
don't have to go hunting through the source to find out.
