Comment (by ReidH):
I found two headers that seemed to pertain to this ticket.
headers/posix/math.h and /system/libroot/posix/glibc/math/math.h.
1, 2, 8 and 9 were added to system/libroot/posix/glibc/math/math.h because
there was a whole commented section requesting them.
3, 4, 5 and 6 were already defined as macros in
system/libroot/posix/glibc/math/math.h so I made no changes.
This confused me, this ticket says it is for headers/posix/math.h, yet a
lot of work seemed like it either needed to be done in, or had already
been done in /system/libroot/posix/glibc/math/math.h.
As for gamma_r and gammaf_r, I found their definitions from Sun, where the
rest of the definitions apparently came from. And with some slight
altering I believed I successfully implemented them in the form of two
files (w_gamma_r.c and w_gammaf_r.c) residing in
src/system/libroot/posix/glibc/arch/generic.
lgammal seemed to already be implemented, and I saw a page on dev.haiku-
os.org that seemed to confirm this.
The only altering made to headers/posix/math.h was the definition of
MAXFLOAT.
I don't know if the two headers are in any way linked, or if everything I
did in /system/libroot/posix/glibc/math/math.h should have been added to
headers/posix/math.h along with redefining all the macros found in
/system/libroot/posix/glibc/math/math.h.
Any help is appreciated.
