ANSI C requires that even the portions of a source file which are eliminated
with CPP conditionals be separatable into CPP tokens.  This is because the '#'
sign is now recognised even if it is not the first character of the line,
unless it is inside a string constant.  I think this is a terrible "feature",
but we'll probably have to live with it.  It looks like I fixed this problem on
our machine by making a copy of vuid_event.h in
/usr/local/lib/gcc-include/sundev/vuid_event.h which gcc looks for first and
replacing the single quote mark on line 42 with two quote marks:

        have to be concerned.  In fact, the vuid interface doesn''t

Looks like another candidate for the ERRATA file.
