Read the standard carefully, particularly 16.2.  16.2 paragraph 2 specifies 
<...> for "headers", while paragraph 3 specifies "..." for "source files".

In the standard (although not in everyday programmer terminology) the term 
"header" means headers from the standard library. It does not mean user 
"source files".  Thus it is technically undefined behavior to use <...> to 
include a user source file.

I think that is what makes people unhappy when they see <...> used for user 
files rather than standard library header files.  Technically it is 
undefined behavior.

Do you read 16.2 as giving more latitude?
