Probably so, and I'm sure Ralf will know what it is. However, this is
usually not a very good idea. You have no idea what compiler someone's
going to be using or what warnings it will throw. For instance, passing
-Wall, -Wextra or -ansi to Solaris CC will give a warning. E.g.,
CC: Warning: Option -Wall passed to ld, if ld is invoked, ignored
otherwise
CC: Warning: Option -Wextra passed to ld, if ld is invoked, ignored
otherwise
CC: Warning: Option -ansi passed to ld, if ld is invoked, ignored
otherwise
... So by enforcing strict checking and flagging errors on warnings, you
are making sure that your code cannot compile out-of-the-box on Solaris.
