Alan and team,
Thank you for the quick response. It looks like the _BSD_SOURCE and
_SVID_SOURCE macros were deprecated back in 2015, in glibc 2.19 and
beyond. Here is more information on the change from { _BSD_SOURCE,
_SVID_SOURCE } to _DEFAULT_SOURCE:
https://man7.org/linux/man-pages/man7/feature_test_macros.7.html
https://stackoverflow.com/questions/29201515/what-does-d-default-source-do
I modified /usr/lib64/X11/config/linux.cf and made these changes. I will
be testing these changes as part of the TightVNC build. I will let you
know if I encounter any issues.
Thank you again,
Ken Zalewski
