+Subject: Fix build with Qt 5.14
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Summary:
+Trying to build kdevelop-pg-qt with Qt 5.14 results in an error:
+```
+.../kdev-pg/kdev-pg-regexp.cpp:44:23: error: redefinition of ‘struct std::hash<QBitArray>’
+     template<> struct hash< type >                          \
+                       ^~~~~~~~~~~~
+.../kdev-pg/kdev-pg-regexp.cpp:53:1: note: in expansion of macro ‘q_Hash_to_tr1_hash’
+ q_Hash_to_tr1_hash(QBitArray)
+ ^~~~~~~~~~~~~~~~~~
+In file included from .../prefix514/include/QtCore/qvector.h:47:0,
+                 from .../prefix514/include/QtCore/QVector:1,
+                 from .../kdevelop-pg-qt/include/kdev-pg-char-sets.h:36,
+                 from .../kdevelop-pg-qt/kdev-pg/kdev-pg-regexp.cpp:20:
+.../prefix514/include/QtCore/qhashfunctions.h:209:1: note: previous definition of ‘struct std::hash<QBitArray>’
+ QT_SPECIALIZE_STD_HASH_TO_CALL_QHASH_BY_CREF(QBitArray)
+ ^
+```
+
+std::hash<QBitArray> is already specialized in Qt 5.14, so avoid redefinition with conditional compilation
+
+Test Plan: try to build with Qt 5.14
