Fields, unions, and code quality

Does using fields of auto variables of union type generate code that is less efficient than it would be using scalars? That is, if in C++ I declare my variables as foo() { union { int n; }; ... } as opposed to simply foo() { int n; ... } would gcc generate inferior code? Or,

C99 _Complex support in gcc

Hi, I checked gcc's C99 status page today and noticed that C99 conformance seems to evolve rather slowly. Most importantly for me, support for complex data types is marked as broken for several years now. Is there any hope that this might change in the foreseeable future? Thanks, Martin --

state of decimal float support in GCC

Support in GCC 4.2 for decimal floating types is based on drafts of ISO/IEC WDTR 23732, which continues to change. There are some differences between the most recent draft N1176 and what GCC implements, and some other things that should probably change or at least be documented. I'd appreciate so
