cryp.to ac-archive's C++ Support (released)
If the compiler accepts the old for scoping rules (the scope of a
variable declared inside the parentheses extends outside the
for-body), define HAVE_OLD_FOR_SCOPING. Note that some compilers
(notably g++ and egcs) support both new and old rules since they
accept the old rules and only generate a warning.
[AC_CACHE_CHECK(whether the compiler accepts the old for scoping rules,
AC_TRY_COMPILE(,[int z;for (int i=0; i < 10; ++i)z=z+i;z=i;return z;],
if test "$ac_cv_cxx_old_for_scoping" = yes; then
AC_DEFINE(HAVE_OLD_FOR_SCOPING,,[define if the compiler accepts the old for scoping rules])
