Hi Adam,
according to the Autoconf manual (8.1 M4 Quotation) that should be
AS_IF([test "$GCC" = yes],
[AS_IF([test "`$CC -v 2>&1 | grep -c 'clang_version'`" != "0"],[CLANG_CC=1])],
[CLANG_CC=])
i.e., exactly one level of quotes for each macro argument. In addition it
might be safer to replace
test "$GCC" = yes
by
test "X$GCC" = Xyes
and similar.
