STLplus C++ library collection SVN stlplus3

Put bodies of operator<< in stlplus namespace - should have been there all along, caught by Borland compiler, other compilers seem to have fixed this silently

Disabled more irritating warnings from Borland compiler

Missing include of stdio - caught by Borland, should be in all versions

Missing include of ctype - caught by Borland, should be in all versions

Borland compiler could not cope with using derived class on template function requiring base class - so expanded print-to_string for all three variants

Fixed to work with the Borland compiler which has a broken version of bitset

Ported to the Borland compiler - does not support typename keyword and has limited support for where in the syntax typenames can be used - only declaration specs, not expressions

Disabled more irritating warnings from Borland compiler

Preferred for of macro test

Ported to Borland compiler - string interpreted as null-terminated which is wrong; should be able to contain nulls so I had to write my own copy routine - also Borland implements archaic convention that initialising with "= *this" takes over memory management, so replaced all instances
