Some strange headers are installed with qt.

Next strange headers are installed to my system with git version of qt: btree.h crc32.h debian_qsql_odbc.h deflate.h ftglue.h ftxgdef.h ftxgpos.h ftxgsub.h ftxopenf.h ftxopen.h hash.h inffast.h inffixed.h inflate.h inftrees.h jri.h jri_md.h jritypes.h moc_yacc.h npapi.h npupp.h opcodes.h os.h otlbuffer.h pager.h parse.h pngasmrd.h pngconf.h Also all private headers are installed to include dir as well as to include/private. This is a BUG? Or they are used by something? At least hash.h breaks compilation of kopete with jabber protocol. My configuration string: ./configure -sm -thread -stl -system-libjpeg -verbose -largefile -qt-imgfmt-jpeg -qt-imgfmt-mng -qt-imgfmt-png -tablet -system-libmng -system-libpng -xft -platform linux-g++ -xplatform linux-g++ -xrender -prefix /usr/qt/3 -libdir /usr/qt/3/lib64 -fast -no-sql-odbc -L/usr/lib64 -no-nis -no-sql-mysql -no-sql-psql -no-sql-ibase -no-sql-sqlite -no-cups -disable-opengl -release -no-g++-exceptions -no-xinerama -system-zlib -qt-gif -ipv6 -dlopen-opengl
