Re: gcc 3.1 and gdb 5.2?

["Dylan Cuthbert" <dylan at q-games dot com>]

Hello there,

My next stop was going to be the gdb and cygwin lists, however, gcc is the
more complicated and experimental of the other two and I wanted to see if
anyone else was experiencing problems on other platforms too.

I compiled and installed the latest binutils which contains ld of course,
do you think it might be a problem with ld on cygwin?   If so, I'd better
add "ld" to my list of mailing lists to post to :-(

I haven't re-compiled cygwin itself into the dwarf2 format (don't know if
its possible), do you think there might be problems with the linker linking
together 2.95-3 compiled older libraries with 3.1 compiled dwarf2 ones?

Regards
