Configure: add defs summarizing doublekind/longdblkind

For windows/netware It seems that many of the recent fp definitions
have not been yet copied over there [1] [2], so went mostly by dead
reckoning [3].

[1] Note that many of them are not absolutely necessary for building.
[2] The proper updating involves doing stuff in win32, which I do not have.
[3] As far as I can tell, Windows CE does not really not have long double.
