BR: gcc vs gcc-c++

Hi, Ruby currently fails to build due to removal of GCC from buildroot. The build failure is due to one test case [1] which fails now and which should be probably fixed to pass even without GCC. However, digging into this, I wonder if Ruby should have "BR: gcc" or "BR: gcc-c++". The thing is, that Ruby is checking presence of C++ compiler during its configuration phase. When I was asking upstream what is the reason for that [2], the answer was that some extension/gems might use C++. Generally, for distribution purpose, I think that it does not really make sense and every extension should be configured separately, therefore we should have just "BR: gcc", i.e. no C++ compiler available during build. However, I am not really sure if this is going to break something or not. I have tried to build rubygem-eventmachine at it seems to build just fine, but what else might be broken? Anyway, for now, I'll probably stick with "BR: gcc" and we can change to "BR: gcc-c++" later, if we discover it causes real troubles.
