Comment (by devans@…):

 Although source highlighting is technically optional in gtk-doc, it is
 used extensively in GNOME API docs so I'm not so enthusiastic about just
 turning it off.

 As stated above, the problems are
   * source highlighting is a build option for vim and so is not always
 enabled.  This may also be version dependent. At any rate, the vim port
 has the circular dependency problem (can this be fixed?).
   * source-highlight and highlight both use boost. Even if we avoid using
 these, there are other boost based ports (e.g. inkscape, gimp2) which must
 not build on the earlier platforms if boost won't build there (but I
 haven't heard any complaints and don't have an appropriate test
 environment).

 The gtk-doc configure file prefers source-highlight and is least happy
 about vim hence the current choice.  The earlier version of the port
 (without source-highlight) did not disable source highlighting so
 configuration fell back to system vim if source-highlight or highlight
 were not used.  I'm not sure if disabling source highlighting altogether
 will just eliminate the highlighting from generated documentation or cause
 a build failure.  Will take a look.

 Best would be to fix boost on the earlier platforms but I realize that may
 be problematic.  Otherwise, looks like disabling source highlighting on
 10.5 and earlier may be the least offensive alternative if it doesn't
 break anything.
