+
+ * matriz.C: add using directives when needed for C functions
+ declared in std:: namespace.
+
+ * math_macrotemplate.h: do not use explicitely std::string, but
+ string.
+
+ * math_macroarg.C: avoid bringing the whole std:: namespace in
+ global-land. When you do that, there is an ambiguity between
+ lyxstring and std::string (which may be defined at the same time).
+
+ * formula.C (HandleExtern): add .c_str() to .str() (useful when
+ using lyxtring)
