Under ANSI, the return value on error from fputs() is an EOF, the
return value if no error is "nonnegative".

In older versions (e.g.: on Apollos; and on Ultrix boxes,
which prove that "older" is not necessarily noncontemporaneous
with "current" :) there doesn't seem to be any mention of
fputs(3)'s having a return value.  It seems logical that
fputs() might have returned 0 on failure and nonzero on
success, such that `if ( fputs(...) )' might work.

In your case, the WP seems to depend on the "older" return
value.  Go through and see if you can find where they've
assigned or compared the return value of fputs() with anything.

try

	egrep '=.*fputs|fputs.*=' *.[ch]

in the source directory.
