This assumes the user's C compiler supports statement expressions. This 
may be going a bridge too far: although statement expressions are 
supported by every C compiler I know of in common use with glibc, they 
are not part of the C standard and if we make this change we might 
exclude compilers we don't know about, or exclude future compilers. 
Also, starting to use statement expressions now might run into bugs in 
existing non-GCC C compilers.

If we are to make changes like this, there should be a NEWS item about 
it, and it should be documented in the manual (as per my previous email 
in this thread).
