No fenv.h ?

[Aioanei Rares <bsdlisten%gmail.com@localhost>]

Hi, trying to compile a program on -current which needs a macro defined 
in fenv.h, but apparently, the file isn't there. Any plans to port the 
missing c99 headers to NetBSD? I would very much like to use it on my 
development machine, but I need fenv.h. Would like to help if I can.
