No warnings show up when importing the offending module:

[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from sympy.mpmath import specfun

So what could be suppressing the warning?
a bug in Python 2.5, it seems:
> more f1.py
as = 1
as = 2
as = 3
> python f1.py
f1.py:1: Warning: 'as' will become a reserved keyword in Python 2.6
f1.py:2: Warning: 'as' will become a reserved keyword in Python 2.6
f1.py:3: Warning: 'as' will become a reserved keyword in Python 2.6
> more f2.py
as = 1
import os
as = 3
> python f2.py
f2.py:1: Warning: 'as' will become a reserved keyword in Python 2.6
A quick look in parsetok.c reveals that it sets a "handling_import" flag
when it stumbles upon an "import" statement, a flag that's later used to
suppress the warning message. The bug is that the flag isn't reset
until the parser sees an ENDMARKER token (end of file), instead of when
it sees the next NEWLINE token.
(if someone wants to submit this to bugs.python.org, be my guest)
