Hi, > Actually, the correct approach would be to avoid defining > _BSD_WCHAR_T_ when compiling C++. This way, it only needs to be done Hmm. I guess this was a workaround for gcc2.x which was not C++ conform. Will old programms still build then ? > once for each platform, rather than once for each header that is > required to declare wchar_t. (Not defining _BSD_WCHAR_T_ tells the > other header files that this type is already defined somehow so they > don't need to declare it again.) How do you like to do this whichout breaking gcc2 support ?. How about this: Another header which is included from include/runetype.h, include/stdlib.h, include/stddef.h, include/inttypes.h include/wchar.h which just contains: #ifdef _BSD_WCHAR_T_ #if !defined(__cplusplus) #if __GNUC__ <= 3) || (__GNUC_MINOR__ <= 97 typedef _BSD_WCHAR_T_ wchar_t; #endif #endif #undef _BSD_WCHAR_T_ #endif Martin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
