DWDS/Dialing Concordance Code

+ better error reporting in CDDCBranchServer::GetFirstHitsFromCorpora()
- report errors parsing 'get_first_hits' responses
- literal TABs in count-key metadata fields can trigger this
- was resulting in silent nstatus_=neProtocolError and empty count-responses from branch server

+ v2.0.40-pre : added autoconf checks for uint(16|32|64)_t; changed QWORD typedef to use uint64_t
- compatible with current size conventions on both 32- and 64-bit systems, but more consistent and should be safer in general

+ ddcVersion.h api doc fix

+ convert_to_utf8.perl: still buggy

+ tagged ddc-2.0.39

+ removed DEBUG_HIT_JSON again

+ v2.0.39: ignore empty breaks in CQueryNode::ConvertOccurrencesToHits() and CQueryNode::ConvertOccurrencesToHitsForPatterns()
- bogus index data containing empty sentences was generating bad empty hits
- specifically, c4_chtk for query: @Apfel #sep #has[title,'Anonymus Kalorien']
- alterantive: remove empty breaks from existing index with new scripts/remove_empty_borders.perl

* fixed json2kwic.perl buglet

+ tagged v2.0.38

v2.0.38 release
