The problem here is the line
if test xyes != x && echo yes | gcc -E -Wdeclaration-after-statement -
2>&1 | grep yes
/dev/null ; then
at lest the versions of gcc that do not provide that -W do not check
the -W arguments when compiling with -E
thus making the test pointless.
if test xyes != x && echo yes | gcc -E -Wi-just-made-this-warning-up -
2>&1 | grep yes
/dev/null ; then
also successfully passes through older gcc and enters the then-arm.

for this doesnt work properly for
GCC versions which do not support this -W directive.
Eventhough it is not supported by GCC
AC_MSG_CHECKING(to see if we can add '-Wdeclaration-after-statement'...
still adds it to the compile flags.
I will see if i can figure out why the test fails.
Me and automake/configure are not on friendly terms.
