[Crash-utility] eppic extension doesn't build with recent master
Hello,
i'm trying to build the recent master branch of the crash utility and
not able to build eppic extension.
The build failure on x86_64 Fedora 34

Exactly the same problem is occurring on s390 architecture.
I find it's very weird that a C library like eppic is including a C++
header from GDB.
gdb-10.2/gdbsupport/common-defs.h is a C++ header containing includes of
other C++ headers like cstdlib, array etc. Furthermore, it contains C++
templates !
Has anybody tested this ? Maybe i'm doing something wrong :/
Would appreciate any hint how to fix this. So far i haven't figured out
howto fix this and we depend on eppic extension.
Thanks
Regards
Alex
