70f47eb720 I don't get Adriano's observation, but I assume it's true. I restore Dmitry's code without the const: VC6 can't delete const data. 2006-04-29 05:41:31 +00:00
robocop
dbea8030f4 MSVC6 says: 
error C2664: 'delete' : cannot convert parameter 1 from 'const class VaryingString *' to 'void *'
        Conversion loses qualifiers
So maybe the rules changed for VC7. Anyway, I simplified the logic here to achieve the same in a direct way.
