New issue 38 by suyash.k...@gmail.com: Issue during cross compilation of
open-vcdiff for powerpc-linux
http://code.google.com/p/open-vcdiff/issues/detail?id=38

What steps will reproduce the problem?
1. Configure open-vcdiff to be compiled for powerpc by using
--host=powerpc-linux option with ./configure in the spec file.
2. start the compilation by going into the root directory of your linux
platform powerpc project and use the commands:
make -C build open-vcdiff.addpkg
make -C build open-vcdiff
3. The compilation starts but throws a compilation error.


What is the expected output? What do you see instead?
The compilation is supposed to complete and produce a cross compiled RPM
for powerpc. Instead we see error like this:

What version of the product are you using? On what operating system?

I am using open-vcdiff-0.8.3 compiling for WindRiver linux for powerpc
architecture.

Please provide any additional information below.
I am guessing that it can be result of improperly defined macros in the
programs where the above function calls cannot be made because maybe they
are not defined for powerpc. I will have to look up the code for this. If
anyone has faced a similar issue Please help me with this. I am stuck
without a way forward.
