I downloaded the source-code of the exiv2 library, but compiling the
files with Microsoft Visual C++ 6.0 produces lots of errors, mostly
in the header files.
Errors occurr at overriding and overloading functions, which differ
only in their return type, e.g. function clone() in the classes
derived from class Value; functions getValue() in the class ValueType.
(According to online-help, overriding and overloading functions
differing only in return type is not allowed.)

Can somebody help me. How can I compile the library with MS VC++ ?
