#7007: Implement missing <math.h> functions
----------------------------+-----------------------------
Reporter: scottmc | Owner: nobody

----------------------------+-----------------------------
These are present in the math.h header, but not yet implemented:
math.h:
lgammal
gamma_r
gammaf_r
The following issues also need to be adressed in math.h:
1. Missing definition of float_t and double_t as described at
opengroup.org.
2. Missing declaration of FLT_EVAL_METHOD.
3. Function "int isgreater(real-floating x, real-floating y);" is never
defined or declared in the header.
4. Function "int isgreaterequal(real-floating x, real-floating y);" is
never defined or declared in the header.
5. Functions "int isless(real-floating x, real-floating y);,
int islessequal(real-floating x, real-floating y);,
int islessgreater(real-floating x, real-floating y);" are never
defined or declared in the header.
6. Function "int isunordered(real-floating x, real-floating y);" is never
defined or declared in the header.
7. There is no definition of "MAXFLOAT" constant in the header.
8. The following optional macros "FP_FAST_FMA, FP_FAST_FMAF,
FP_FAST_FMAL" are not defined in the header.
9. The following macros "FP_ILOGB0, FP_ILOGBNAN, MATH_ERRNO,
MATH_ERREXCEPT, math_errhandling" are never defined in the header.
The functions need to provide the requirements as defined at:
http://www.opengroup.org/onlinepubs/9699919799/basedefs/math.h.html
This is being worked on by a GCI student.
This is for the math.h in headers/posix/math.h
