yes it is the case here.
It uses ceil or floor or sqrt or some other common math function.

All this change did is add a configure argument.  How the .pc get built
is done by the pango configure & makefile.  It's not a dragonfly thing.
 If pango pc gets -lm due to this configure argument, it's because pango
knows that it's needed when explicit linking is required.
