[PATCH 1/1] dpkg: fix include header caused compile error

[Kai Kang]

Build dpkg-native on Fedora 19, it fails with:

/usr/include/c++/4.8.1/cstdlib: In function ‘long long int std::abs(long long int)’:
/usr/include/c++/4.8.1/cstdlib:174:20: error: declaration of C function ‘long long int std::abs(long long int)’ conflicts with
   abs(long long __x) { return __builtin_llabs (__x); }
                    ^
/usr/include/c++/4.8.1/cstdlib:166:3: error: previous declaration ‘long int std::abs(long int)’ here
   abs(long __i) { return __builtin_labs(__i); }
   ^

That because header cstdlib is included in a 'extern "C"' block that gcc
4.8 doesn't support. Fix it by move the header file out of the 'extern "C"'
block.
