No, nested functions are not allowed in standard C.
It looks to me like the macros were originally written so that the first
argument was supposed to be an lvalue to receive the result, and they were
not supposed to be used in an expression context. To make the
block-expression wrappers work, I think the basic
VALGRIND_DO_CLIENT_REQUEST() macro will have to be changed to return a
result rather than take an lvalue.
