[FFmpeg-devel] [PATCH] avfilter/vf_tonemap: don't use NAN constant as an initializer

"The macro NAN is defined if and only if the implementation supports
quiet NaNs for the float type. It expands to a constant expression of
type float representing a quiet NaN."

-> If the macro is defined, it must be a compile-time constant.
Therefore, DJGPP is wrong.

I say let the people who care about DJGPP fix it, and in the meantime
use "--disable-filter=tonemap".
