> Manipulating compiler flags is a very common need indeed and could use some help from rpm, but that need is not limited to %optflags, there are various other similar things as well and I certainly don't want separate macros for updating %build_cflags, %build_cxxflags, %build_ldflags and so on.

To be honest, I'm not much familiar with `m4` language and how `rpm` works. Can you please help me how should such macro look like? Should it take the variable name as a first argument?

I'm open for a better-defined API. Can you help me with that as well?
