libreplace: add a missing "eval" to the AC_VERIFY_C_PROTOTYPE macro

Without this eval, upon test success the corresponding actions
(like defining corresponding variables) are not taken.

Found by Timur I. Bakeyev, and based on his patch for 3.5.

PIDL: fix parsing linemarkers in preprocessor output

When PIDL calls out to C preprocessor to expand IDL files
and parse the output, it filters out linemarkers and line control
information as described in http://gcc.gnu.org/onlinedocs/cpp/Preprocessor-Output.html
and http://gcc.gnu.org/onlinedocs/cpp/Line-Control.html#Line-Control

With gcc 4.8 stdc-predef.h is included automatically and linemarker for the
file has extended flags that PIDL couldn't parse ('system header that needs to
be extern "C" protected for C++')

Thanks to Jakub Jelinek <jakub@redhat.com> for explanation of the linemarker format.
