[Bug c/15238] New: Warn about variable declarations mixed with code

[arend dot bayer at web dot de]

It would be extremely useful to have an option (below -pedantic) which triggers 
a warning in the testcase. Mixing variable declarations with code is the most 
frequent cause of breaking backwards compatibility for compilation with gcc 
2.95 in projects that are supposed to be compilable by all gcc versions (using 
gcc extensions), but where the developers are using gcc 3.x. 
 
I have seen this issue on many mailing lists.
