           Version: Latest

This is on 14.0-CURRENT.
HAVE_MEMPCPY is undefined in third_party/nasm/include/compiler.h, resulting in
messages such as:

In file included from ../../third_party/nasm/asm/directbl.c:6:
In file included from ../../third_party/nasm/asm/directiv.h:9:
In file included from ../../third_party/nasm/include/perfhash.h:37:
../../third_party/nasm/include/compiler.h:249:21: error: static declaration of
'mempcpy' follows non-static declaration
static inline void *mempcpy(void *dst, const void *src, size_t n)
                    ^
/usr/include/string.h:70:7: note: previous declaration is here
void    *mempcpy(void * __restrict, const void * __restrict, size_t);
         ^
1 error generated.

My crude and simple patch involve commenting out the offending prototype in
third_party/nasm/include/compiler.h. A better patch would be to ensure
HAVE_MEMPCPY is defined all the way.

Log file and patch will be attached soon.
