To: systemtap; +Cc: Sergei Trofimovich
Without the change systemtap build fails on weekly gcc-12 as:
util.cxx: In function 'void ltrim(std::string&)':
util.cxx:1766:56: error: 'std::pointer_to_unary_function<_Arg, _Result> std::ptr_fun(_Result (*)(_Arg))
[with _Arg = int; _Result = int]' is deprecated: use 'std::mem_fn' instead [-Werror=deprecated-declarations]
1766 | std::not1(std::ptr_fun<int, int>(std::isspace))));
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~
The change uses lambda to express the predicate.
