#388 closed enhancement (fixed)

use fifth argument [action-if-cross-compiling] in AC_RUN_IF_ELSE

Reported by: Peter Owned by: Jari Häkkinen
Priority: trivial Milestone: yat 0.5
Component: build Version: trunk
Keywords: Cc:


We use macro AC_RUN_IF_ELSE twice in to test for quiet_NaN and infinity with a comment

# At run-time, but this has the disadvantage that yat cannot be built  
# for cross-compilation

However, there is a fifth argument available in the macro to be used when $cross_compiling=yes. I wonder if it wouldn't make sense to use this argument and fall back on compilation tests when cross compiling. For instance, for quiet_NaN there is already a compilation test checking if std::numeric_limits<double>::quiet_NaN() is available.
