The pwd.h header now contains this: #if __XSI_VISIBLE >= 500 struct passwd *getpwent (void); void setpwent (void); void endpwent (void); #endif The default settings per the sys/cdefs.h header are: #define __POSIX_VISIBLE 200809 #define __XSI_VISIBLE 700 #define __BSD_VISIBLE 1 #define __ISO_C_VISIBLE 2011 unless your environment defines one of _XOPEN_SOURCE _POSIX_C_SOURCE _ANSI_SOURCE _C99_SOURCE _C11_SOURCE _GNU_SOURCE Have a look at the end of /usr/include/sys/cdefs.h, it explains things.

thanks for the hints for what I can see "_GNU_SOURCE" is defined in both cases at configure stage and reported in config.status and config.h I will look to compare the preprocessor output to see why building on 1.7.28 the "/* Everything and the kitchen sink. */" is not pulled in Regards Marco -- 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
