Can you give some information on the type of hardware and operating
system you're using?

The INSTALL file is only for building GNU make from a distributed source
tarball, say from ftp.gnu.org.  If you want to build from Git you must
read the README.git file and follow those directions.

That message means that while make was printing information to stdout
(note that the only things make itself prints to stdout during a normal
runtime are the "entering/exiting" lines, plus the command line it will
invoke for each rule where it isn't suppressed), the fprintf() command
got an error and wasn't able to write its output properly.

This error comes from the C runtime library and denotes some kind of
error writing content to stdout.  I don't see, offhand, how there could
be any bug in GNU make that would cause this problem.

Is there anything unique or unusual about the way you're invoking make,
with respect to its stdout?  Are you writing the output to a file using
redirection?  Reading the output using a pipe (piping make's output to
another program)?  Something else?
