- source files and Makefiles need never be executable
- scripts are run directly by their interpreters in the
test suites, so also do not need to be executable
SF Bug#1292 - Runtime fixes for Proc changes in ruby-1.9 when using STL wrappers that override the default predicate, such as:
%template(Map) std::map<swig::LANGUAGE_OBJ, swig::LANGUAGE_OBJ, swig::BinaryPredicate<> >;
Fixes li_std_functors testcases for Ruby 1.9.
Also rb_respond_to return values have changed subtely in 1.9 and return should be treated as a flag instead of checking for Qtrue, see SF Bug #1159.
Also fix li_std_map, li_std_set silently failing - rb_protect behaviour seems to have changed when an exception is thrown, so code has been changed to use rb_rescue. A call to 'rb_set_errinfo(Qnil)' could have solved this after the rb_protect call, but it is only available in 1.9+ and Ruby API changes are not easily and transparently detectable.
