What you guys feel about anonymous unions? I happened to committed some code with anonymous unions, but it caused gcc to choke when -std=c99 option is specified, which is only specified with automake but scons.
After some search, it looks like anonymous unions are not part of C99, but are part of C++ and will reportedly be part of C1X [1]. I think all major compilers support it. I heard they are also often used together with bit fields to describe hardware registers. But for this to work to gcc we need to remove -std=c99, or replace with -std=gnu99, or pass -fms-extensions together with -std=c99. I don't care much either way. I'd just like to hear what's the general opinion on this to avoid ping-ponging on this matter.
