D.gnu - Test if errno.h is available for some platforms

reply Vincent Richomme <forumer smartmobili.com> writes:
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 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
