    configure: Split valgrind test into pragma test and valgrind.h test · 06d71fa1
    Peter Maydell authored
    Split the configure test that checks for valgrind into two, one
    part checking whether we have the gcc pragma to disable unused-but-set
    variables, and the other part checking for the existence of valgrind.h.
    The first of these has to be compiled with -Werror and the second
    does not and shouldn't generate any warnings.
    
    This (a) allows us to enable "make errors in configure tests be
    build failures" and (b) enables use of valgrind on systems with
    a gcc which doesn't know about -Wunused-but-set-varibale, like
    Debian squeeze.
