GNU make does print the signal number as long as it can determine the
right one.  If you are seeing this, then it means GNU make got a signal
it couldn't translate.  This often means that the configuration for your
system was inaccurate, or that your system doesn't provide proper signal
translation facilities.

Since you don't specify what type of system you're working on I can't
give more help than that, but your next example seems to imply it's DOS,
Windows, or similar.  In that case you should check on the
address@hidden mailing list and see whether signal translation has
been ported to work on DOS/Windows platforms.

  jg> z:\bin\make.exe: *** [mak19] Error 255

It is not appropriate for make to translate this code into an errno
value, because it is _NOT_ an errno value.

This code is the return value from the program that make invoked, and
that return value is virtually never an errno value.

In the example you give here, for example, the invoked program exited
with a -1 exit code, which is not a valid errno value.
