Doxygen /**< ... */ style comments cause macro expansion issues

[sebhub]

The /**< ... */ Doxygen style is used in 1000s of define documentations. However, if MACRO_EXPANSION is set to YES, then this documentation is added to the scope where the define is expanded. See also: https://github.com/doxygen/doxygen/issues/11158.

A sed -i 's,/\*\*<\(.*\w\) *\*/,//!<\1,' <all files with Doxygen comments> would fix the issue.
