egcs 1.1.1 : debug mode support for SGI IRIX5.3

[Pasha Murat]

Dear EGCS developers, 
	 I'm wondering if support of debug (-g) mode has been discontinued 
in EGCS 1.1.1 for SGI IRIX 5.3 . For some reason I'm failing to use gdb 
with the code compiled by EGCS 1.1.1 (see output below), this was definitely
not the case for the previous (1.1b) release.

		I'd appreciate any hints and comments,  thanks a lot, pasha
