Hi, cygwin64 shares for 64-bit the ABI of Windows native. This is caused by different reasons (eg. unwind-table description for prologue, etc). So for Windows targets va_list is indeed of 'char *' type. And this is ok. The variant of x86_64 abi, which uses indeed a structure-variant for variadic-arguments plus some call-abi extensions, isn't recommented for on Windows. If your linux code relies on structure-variadic x86_64-ABI, it seems to me broken, and needs to be ported.
Hope this answers your question. Regards, Kai -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
