Re: Headers and templated classes

[David Sugar]

The reason they were in a seperate directory originally was that they came 
about late in the development of Common C++ and so idea of having a Common 
C++ template library was new.  However, the throught at the time was also 
that there were still many C++ compilers in production use that generate 
template code poorly or incorrectly, and so I thought it was best to make it 
easy to isolate any template classes from the rest of the library if one 
simply did not want to make use templates at all or had poor or broken 
compilers.  Even today, none of the core libccgnu2 classes make use of any 
template code, although templates are found in some things in libccext2.
