+       * configure.in: use LYX_CXX_STL_MODERN_STREAMS; check for headers
+       <ostream> and <istream>.
+       
+       * acinclude.m4 (LYX_CXX_STL_MODERN_STREAMS): new test. Checks
+       whether <fstream> provides the latest standard features, or if we
+       have an oldstyle library (like in egcs).
+       (LYX_CXX_STL_STRING): fix the test.
+
+       * src/support/DebugStream.{C,h}: use L{I,O}stream.h and condition the
+       code on MODERN_STL_STREAM.
+
+       * src/support/lyxstring.h: use L{I,O}stream.h.
+
+       * src/support/L{I,O}stream.h: new files, designed to setup

+         - puts std::ostream and std::endl (for LOStream.h) or
+         std::istream (LIStream.h) in toplevel namespace.
