[ https://svn.apache.org/r1518337 ]
QPID-5102: C++ Broker Windows build with PROTON needs new _EXTERN statements.
Note that this patch supplies only _EXTERNs. It does not change the build for
finding PROTON nor does it correct the QPID-5100 amqp/amqpc library export
issues.
> C++ Broker windows build exports amqp library classes in qpidcommon dll

> Key: QPID-5100
> URL: https://issues.apache.org/jira/browse/QPID-5100
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: 0.22
> Environment: Windows build
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
>
> The symbol export mechanism for the ampq library has an issue whereby all the
> exported symbols for amqp.dll are linked into qpidcommon.dll and exported
> from there.
> To expose all the exports use:
> {noformat}
> cd qpid/cpp
> find . -name "*.h" | xargs grep _EXTERN
> {noformat}
> The *_EXTERN then indicates for each symbol which export library the symbol
> originates. The symbols in question are all the ./amqp/ symbols pegged with
> the QPID_COMMON_EXTERN. For example:
> {noformat}
> ./amqp/Decoder.h: QPID_COMMON_EXTERN Decoder(const char*, size_t);
> ./amqp/Decoder.h: QPID_COMMON_EXTERN CharSequence readSequence8();
> ./amqp/Decoder.h: QPID_COMMON_EXTERN CharSequence readSequence32();
> {noformat}
> The fix for this problem is to copy one of the ImportExport.h pattern files
> and make it work for compiler symbol amqp_EXPORTS. Then change all the
> QPID_COMMON_EXPORTS in /amqp/*.h to QPID_AMQP_EXPORTS.
