[Numpy-discussion] Warnings in NumPy SVN

I want to apologize for the relative instability of the SVN tree in the 
past couple of days.  Getting the scalarmath layout working took more 
C-API changes than I had anticipated.  

The SVN version of NumPy now builds scalarmath by default.  The basic 
layout of the module is complete.  However, there are many basic 
functions that are missing.  As a result, during compile you will get 
many warnings about undefined functions.   If an attempt were made to 
load the module it would cause an error as well due to undefined symbols.

These undefined symbols are all the basic operations on fundamental c 
data-types that either need a function defined or a #define statement made.

The names have this form:

@name at _ctype_@oper@

where @name@ is one of the 16 Number-like types and @oper@ is one of the 
operations needing to be supported.

The function (or macro) needs to implement the operation on the basic 
data-type and if necessary set an error-flag in the floating-point 
registers. 

If anybody has time to help implement these basic operations, it would 
be greatly appreciated.
