- Smaller C: fix a bug in __func__ introduced with
float-related changes
- make *printf() print floats greater than 1e25
- make *printf() print the plus sign when the format
includes "+", e.g. printf("%+f\n", 1.0);
- clean up and complete prototypes in <math.h>
- remove non-standard HUGE and LOGHUGE from <math.h>
- add HUGE_VAL to <math.h>
- express some hard-coded limits in terms of constants
from <float.h>
- uncomment prototypes of several floating point
conversion functions in <stdlib.h> for Smaller C

Floats in Smaller C!
...
double is an alias for float. IOW, only 32-bit
single precision floats are supported. This isn't
conformant, but OK for some embedded systems (e.g.
RetroBSD) and simple compilers like this.
Also, the following operators are not supported with
floats at the moment: ++, --, +=, -=, *=, /=.
But +, -, *, /, =, ||, &&, ?:, !, comparison, casts,
if/while/for are OK.
