           Summary: v2.067 fails to build with musl libc (on alpine linux)

small patch to fix compilation under musl libc.

when building 2.0.67.1 with g++ version 4.9.2/musl libc (on alpine linux 3.2
stable), compilation fails in root/port.c -- seems to be using glibc specific
headers.

the error message is:

root/port.c:586:22: fatal error: bits/nan.h: No such file or directory
 #include <bits/nan.h>
                      ^
compilation terminated.
posix.mak:391: recipe for target 'port.o' failed
make: *** [port.o] Error 1

the attached patch "fixes" these errors but not sure if it is the correct way
to go about it. It does produce a working dmd executable that prints the help
message.
