I spotted an "error" while building dmake (on Windows and Linux).
Maybe it is only cosmetic, but I just wanted to report it:
In file included from extern.h:95:0,
vextern.h:37:0: warning: "EXTERN" redefined
In file included from extern.h:94:0,
./unix/cygwin/public.h:52:0: note: this is the location of the previous definition
#define EXTERN extern
But more important, have some nice days for Christmas! ;-)
