System:  Sun 4/330 running SunOS 4.1
Version:  Gdb 4.6 compiled with cc:
	configured sparc-sun-sunos4.1

When compiled using the Sun native C compiler (which is the default in the  
Makefile), the following error occurs:

...because Sun systems do not have a built-in strerror() function.

Here is a very unofficial patch to fix this:
