Description Alan Coopersmith 2004-02-14 18:57:56 UTC 
Forcing _XOPEN_SOURCE to be defined when including <math.h> on Solaris Express
(the pre-release version of Solaris 10) when using a C compiler in C99 mode
(such as Sun Studio 8 cc with the arguments specified in the current imake
configs) results in failing to compile with errors:

"/usr/include/sys/feature_tests.h", line 263: #error: "Compiler or options
invalid for pre-UNIX 03 X/Open applications  and pre-2001 POSIX applications"

Fortunately, Solaris does not require _XOPEN_SOURCE in order to get the 
definitions of hypot or pow, so it can simply be added to the list of defines
to check for skipping the forced definition.

The same fix needs to be applied to programs/Xserver/hw/xfree86/xaa/xaaWideLine.c
if you build with #define LoadableServer NO.   That fix was applied to CVS head on
2004-08-28.
