+ * src/mathed/math_symbols.C, src/support/lstrings.C,
+ src/support/lyxstring.C: add `using' directive to specify what
+ we need in <algorithm>. I do not think that we need to
+ conditionalize this, but any thought is appreciated.
+
+ * many files: change all callback functions to "C" linkage
+ functions to please strict C++ compilers like DEC cxx 6.1 in mode
+ strict_ansi. Those who were static are now global.
+ The case of callbacks which are static class members is
+ trickier, since we have to make C wrappers around them (see
+ InsetError, InsetInfo and InsetUrl). The same holds for friends. I
+ did not finish this yet, since it defeats the purpose of
+ encapsulation, and I am not sure what the best route is.
