| dnl Add a set of flags to WARNING_FLAGS, that enable compiler warnings for
dnl isl. The warnings that are enabled vary with the compiler and only include
dnl warnings that did not trigger at the time of adding these flags.

if test "${ax_cv_c_compiler_vendor}" = "clang"; then
dnl isl is at the moment clean of -Wall warnings. If clang adds
dnl new warnings to -Wall which cause false positives, the
dnl specific warning types will be disabled explicitally (by
dnl adding for example -Wno-return-type). To temporarily disable
dnl all warnings run configure with CFLAGS=-Wno-all.
