+Subject: [PATCH] librewrite: include ldap_pvt_thread.h before redefining
+ calloc
+
+This helps compiling with musl, where sched.h is included by
+ldap_pvt_thread.h which provides prototype for calloc() and conflicts
+
+/usr/include/sched.h:84:7: error: conflicting types for 'ber_memcalloc'
+| void *calloc(size_t, size_t);
+|       ^1
+|  warning and 1 error generated.
+| ./rewrite-int.h:44:21: note: expanded from macro 'calloc'
+| #define calloc(x,y)     ber_memcalloc(x,y)
+|                         ^
