This is on a Sun-4 running OS4.0.  The Sun compiler seems to be
putting an N_SLINE symbol with a negative line number (-1) immediately
following a library definition ("-lg" in this case). Gdb expects the
source file name to immediately follow and prints the message:
"Invalid symbol data: does not start by identifying a source file."
The attached patch to dbxread.c prevents this message.
