Chiming in with a general comment: dwarf2 exceptions are different than
dwarf2 debug info. However, obviously both varieties of "dwarf2" can
impact gdb.
I finished a build last weekend of gcc trunk with
(1) Steve Ellcey's recently-accepted "pre switch to modern libtool" patch
(2) Steve El

Oh, I didn't know there was anything that specifically mentions -gstabs
in there, just that if you don't set {C,CXX}FLAGS yourself auto

I thought about that, but the problem is anything you do to *FLAGS in
winsup/cygwin won't affect flags used in the other dirs like libiberty
or newlib, and so unl

The attached patch allows for dllfixdbg to copy DWARF-2 debug sections
into the .dbg file. There was also an (accidently?) duplicated section
