having the gamma function, one certainly needs the other Euler constant:
C = 0.5772
the C constant is taken from GSL

for expm1, we use the Taylor development near zero, but
we have to precise what means small value for x. here this means
abs(x) math.log(2.0).
one can also use abs(x) C

finally, for the error function, with the same kind of idea as with expm1,
here is a pure python definition
these patches are against r27a1:76674
if all these make sense, i'll check for NAN, infinity, test suite

may be some error when i send this the first time,
i cannot see the file, so i resend mathmodule.c.diff
sorry if you get it twice

pure Python codes are posted to ASPN:

i also rewrote the patch so that they don't
use the high_word/low_word macros anymore.

i wrote pure Python equivalent of the patch and will
post it to the ASPN cookbook as suggested. i'm wondering
if i have to upload the code here too, or just the link
will suffice?
Raymond Hettinger:
Can you also implement blending

ouch!
i was asleep, at 3AM, when i edited the issue
and didn't really know what i was doing.
i just see that i removed, instead of edited the
mathmodule.diff and didn't check after.
so here it is again, with the url for original code

Mark Dickinson :
So a full patch for this should touch at least Python/pymath.c,
Modules/mathmodule.c, configure.in, Lib/test/test_math.py, and
Doc/Library/math.rst.
here are patches for Python/pymath.c, Modules/mathmodule.c,
Lib/test

and this is the header.
it is stolen from glibc.
