>Description:
A recent commit for graphics/gdk-pixbuf2 patches meson.build to define
-D_XOPEN_SOURCE=500
This kind of definition with a specific number such as 500 for _XOPEN_SOURCE is almost never a good thing on FreeBSD, probably other BSDs. For this case, such a definition causes a simple function such as double round(double) from math.h to no longer be declared.
I believe what happens on FreeBSD is when _XOPEN_SOURCE is defined without a number, sys/cdefs.h will be able to set __BSD_VISIBLE enabling everything to be visible. But once one defines _XOPEN_SOURCE to be some number in the hundreds, __BSD_VISIBLE does not get defined, throwing out visibility of anything not strictly in the standards.
>How-To-Repeat:
>Fix:
Would it be possible to restrict the change to SunOS such as:
@@ -8,7 +8,11 @@ project('gdk-pixbuf', 'c',

Hi!
Can you please try if jperkin's latest commit (bumping it to 600) fixes the problem?
Thanks,
Thomas
