is there a PRAGMA one can use to prevent these 'narrowing conversion' warnings?
Thanks,
Whit
this is gcc 4.6 on debian testing:
../cppbugs/fastexp.h:71:76: error: narrowing conversion of ‘((clipp +
1.2694269561767578125e+2f) * 8.388608e+6f)’ from ‘float’ to ‘uint32_t
{aka unsigned int}’ inside { } [-fpermissive]

Yeah, that seems annoying.
This suggests static_cast is the fix.

Please notice that with clang these warnings become errors.

I thought this was fixed (I added cast.h and sprinkled the code appropriately
with casting operators). I'm using gcc 4.6.3 and not seeing this. Do you have
the latest version of the software?

I think this isn't fixed completely. I'm testing using the latest release. On a
Mac OS 10.9, ./configure && make check fails because clang treat those warnings
as errors.
