Hi,I was doing some experiments and had linking issues with C++ code and saw that some Mesa header files have extern "C" wrappers and others do not. For example running: $ find src/mesa/main -type f -name "*.h" -exec grep -H -E -o -c "extern \"C\"" {} \; | grep :0 | wc -l gives a result of 109 files. However, some header files in mesa/main and other places do have the extern "C" { wrapper, such as mesa/main/mtypes.h. What is the rule, if any, of what files have the extern "C" protection so that the file is suitable for inclusion by C++ source files?
The headers with extern "C" are probably those that get included by the GLSL compiler code (which is in C++). Otherwise, I think extern "C" gets added on an as-needed basis.
