Luc et al,
As I mentioned in the crash-7.0.0 announcement, the build
of the eppic extension module fails due to changes in the
newly-embedded gdb-7.6 tree:
$ make extensions

...
The "redefined" and "reclaration" warnings can be addressed by modifying
the extensions/eppic.mk file by:
(1) removing the "-I.." entirely, and
(2) moving the "../$(GDB)/gdb" so that it is the first gdb directory in the compile line
$ diff extensions/eppic.mk.orig extensions/eppic.mk

And the fatal error can be avoided by this patch to the $(APPFILE),
or eppic/applications/crash/eppic.c:
$ cat /tmp/eppic.patch

With those changes made, the extension module builds OK, albeit with
the following warnings that I'm not going to tinker with -- but it
would be nice if they could be cleaned up:
$ make extensions

make[5]: Nothing to be done for 'all'.

So unless you direct me otherwise, I will queue the "-I" changes to the eppic.mk
file for crash-7.0.1, given that it's part of the crash source tree.
And I'll let you guys ruminate the eppic.c patch shown above and
let you deal with the remaining warnings.
Thanks,
Dave
