Bruno, the patch causes build failures on mingw:
./unistd.h:313: error: conflicting types for 'gethostname'
/usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/../../../../i586-mingw32msvc/include/winsock2.h:635:
error: previous declaration of 'gethostname' was here
The problem is that the native gethostname Win API uses 'int' instead of
'size_t' as the prototype.
Should we replace the system gethostname with a wrapper? Or can we use
a simple #define such as
#define gethostname(name, len) gethostname (name, (int) len)
when using the winsock2.h gethostname definition?
