Nothing strange about that at all; the Sun compiler implements the "#pragma"
directive that appears in recent ANSI C drafts, in order to permit code to
provide "hints" to the optimizer, such as "setjmp can return from another
galaxy, so don't assume you know what values are in the registers when it does
return."  This hint is, in fact, provided in <setjmp.h>.  "makedepend" doesn't
know about this directive, so it pukes.

The following change to "makedepend", which teaches it that "#pragma" exists
(but isn't interesting to it), seemed to work when I built X11R2:
