Subject:Minor patch to null.h
View as plain text  
Our organization changed OS version and compiler (from GCC 3.2.2 to GCC 3.2.3).  As part
of the move, the CM powers-that-be tightened the code requirements such that compiles fail
on any warning.  As a result, our code was choking on a line in null.h where the operator
() function of class null_type was not returning a value (throws BadNullConversion as it
should).  The included patch is what we used to fix the problem in our little world.

This is against 1.7.26; we haven't updated yet.  However I just checked and the patch
should work against the latest code.

Anyway, here's the diff, humbly submitted...:
