Traditionally, every header file had a .h suffix. Thus C++ implementations
provided headers such as <map.h> and <iostream.h>. For compatibiilty, most
When the standards committee needed headers for redefined versions of
standard libraries for newly added library facilities, naming those headers
became a problem. Using the old .h names would have caused compatibilty
problems. The solution was to drop the suffix .h in standard header names.
The suffix is redundant anyway because the <> notation indicates that a
standard header is being named.
Thus, the standard library provides non-suffixed headers, such as <iostream>
and <map>. The declarations in those fiels are placed in the namespace std.
Older headers place their declarations in the global namespace and use a .h
So, the decision is neither arbitrary nor non-standard. The only thing left
is to actually implement namespaces in gcc :)
