 The FAQ entry concerns g++ emitting errors.  I have read the entry and was
 aware of how to reduce the errors to warnings, as I indicated in the
 original report. The FAQ does not document any desire by the GCC team to
 make these warnings impossible to turn off.
 
 The GCC manual describes this flag:
 
 `-Wreturn-type'
      Warn whenever a function is defined with a return-type that
      defaults to `int'.  Also warn about any `return' statement with no
      return-value in a function whose return-type is not `void'.
 
 yet, specifying `-Wno-return-type' does not turn off the warnings in
 question, which are certainly about the kind of functions this warning
 covers.  Why is this not a bug?
 
 I am in the position of supporting an open-source project which produces
 over 150 warnings per file when compiled on Solaris, warnings that can't
 be shut off.  I hope Sun plans to fix their headers, but what if they
 don't? What benefit are these warings to a developer who has done nothing
 wrong or an end-user who just wants to use the program? Why not provide a
 means to turn off the warnings?
