The reason is that some (notably FPU-less) architectures,
|
|
including mips*-nf, don't define/implement some of the
|
|
floating point constants, even though fenv.h is
|
|
available.
|
|
|
|
The key point is:
|
|
A fully standards conforming fenv.h does not have to
|
|
define any FE_* macros, and if it does define them,
|
|
then it defines macros only for the FP exceptions it
|
|
actually supports.
