Test if errno.h is available for some platforms

[David Friedman]

errno.h and snprintf (or _snprintf) should be available -- I just 
downloaded the mingw32ce package and checked.  Can you delete Makefile, 
config.status, and config.cache in the phobos build directory, then try 
building again?  Please email me the resulting config.log
