dpkg: fix include header caused compile error
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.

dpkg defines:
|
||||
#define DPKG_BEGIN_DECLS extern "C" {
|
||||
|
||||
That makes header cstdlib included in a extern "C" block which is not supported
|
||||
by gcc 4.8. It fails on Fedora 19:
|
||||
|
||||
/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); }
|
||||
^
|
||||
|
||||
Move include gettext.h out of the extern "C" block to fix this issue.
