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.
