make: Bugs

 
 1.2 Problems and Bugs
 =====================
 
 If you have problems with GNU 'make' or think you've found a bug, please
 report it to the developers; we cannot promise to do anything but we
 might well want to fix it.
 
    Before reporting a bug, make sure you've actually found a real bug.
 Carefully reread the documentation and see if it really says you can do
 what you're trying to do.  If it's not clear whether you should be able
 to do something or not, report that too; it's a bug in the
 documentation!
 
    Before reporting a bug or trying to fix it yourself, try to isolate
 it to the smallest possible makefile that reproduces the problem.  Then
 send us the makefile and the exact results 'make' gave you, including
 any error or warning messages.  Please don't paraphrase these messages:
 it's best to cut and paste them into your report.  When generating this
 small makefile, be sure to not use any non-free or unusual tools in your
 recipes: you can almost always emulate what such a tool would do with
 simple shell commands.  Finally, be sure to explain what you expected to
 occur; this will help us decide whether the problem was really in the
 documentation.
 
    Once you have a precise problem you can report it in one of two ways.
 Either send electronic mail to:
 
          bug-make@gnu.org
 
 or use our Web-based project management tool, at:
 
          http://savannah.gnu.org/projects/make/
 
 In addition to the information above, please be careful to include the
 version number of 'make' you are using.  You can get this information
 with the command 'make --version'.  Be sure also to include the type of
 machine and operating system you are using.  One way to obtain this
 information is by looking at the final lines of output from the command
 'make --help'.
