memcpy error when compiling cuda=1

[Psy-Fer]

When I compiled on my dev machine, I got the following error:

make cuda=1
nvcc -x cu -g -O2 -std=c++11 -lineinfo -Xcompiler -Wall -I./htslib -DHAVE_CUDA=1 -rdc=true -c src/f5c.cu -o build/f5c_cuda.o
/usr/include/string.h: In function ‘void* __mempcpy_inline(void*, const void*, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
return (char *) memcpy (__dest, __src, __n) + __n;
^
Makefile:76: recipe for target 'build/f5c_cuda.o' failed
make: *** [build/f5c_cuda.o] Error 1

To fix it, set the following line:

CUDA_CFLAGS+="-D_FORCE_INLINES" make cuda=1

I don't really understand how or why this works, but it does.

:)
