GDB 3.4 - Incompatibility with Sun's cc

#316

Author: Tony Li

Configuration: Sun 4/60 (Sparcstation 1), SunOS 4.0.3c, gdb 3.4, 
	gcc 1.36

Problem: gdb does not seem to treat binaries generated by SunOS cc the
	same as binaries from gcc.  

Reproduce by:  Compile the following program with both SunOS cc and
	gcc:
		main () {
			printf ("Hello world.\n");
		}

	Next, debug the resulting binaries, executing the following
	commands in each case:
	
		break main	
		run
		next

	For the gcc compiled binary, after giving the 'next' command,
	the printf executes and the next statement is the final line
	of the program.  For the SunOS cc compiled binary, giving the
	'next' command produces:

		(gdb) next
		0x4084 in etext ()

This problem has to do with dynamic linking, which GDB does not
understand.  Compile with -Bstatic using SunCC and then see what you
get.
