Hi,

It would be useful to know what architecture and linux distribution you are attempting to build oprofile on.The version of /usr/include/libiberty.h on RHEL 7 and Fedora 23 do not have PARAMS in the declaration of expandargv or writeargv.

Looking around for libiberty.h and PARAMS turned up where the PARAMS needed to be defined.

https://gcc.gnu.org/ml/gcc-patches/2004-03/msg00125.html

Also what compiler is being used to build oprofile? I could imagine a case where PARAMS isn't getting set due the compiler being used.
