Hi,

when  trying to cross-compile gdc for wince platform I get an error due to errno.h (errno.h is not available on mingw32ce).
From what I see a test is done via a d\phobos2\config\errno.x3.

Could it be possible to check if platform has errno.h before to start a test.

I have also tried to cross-compile cegcc and I get a configure error in libphobos :

checking for snprintf... no
configure: error: No variant of snprintf.
make[1]: *** [configure-target-libphobos] Erreur 1


I don't understand how libphobos check if there is snprintf because other gcc lib (binutils, intl, libiberty, ...) can find it.

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

This one is a bug in the Makefile.
