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

to do something or not, report that too; it's a bug in the
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

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
