#7569 closed bug (fixed)

Does not correctly detect float/double Haskell types when cross-compiling

As described on the mailing list, the way that the check for floating point types is implemented in aclocal.m4 gives an error in cross-compiling mode and thus fails to detect that float/double are supported.

The possible patch is attached here.

I'd like endorse singpolyma's patch by saying that it works and is needed for cross-compiling.
