Hi,
I got the following error when building stap using old elfutils 0.141.
translate.cxx:4670: error: Dwarf_CFI_Entry was not declared in this scope
The CFI support was added to elfutils since 0.142. Guess we need to
give a warning in configuration or code workaround.
Regards,
Wenji

My fault, I didn't test the new debug_frame dwarf unwinder speedups
against old elfutils. Should be fixed now:
commit 35410c41751ffee9331166ba8e6c3404643b11cf

Guard create_debug_frame_hdr body with _ELFUTILS_PREREQ(0,142).
Thanks,
Mark
