Alternative to __FILE__/__LINE__

[François Dumont]

Hi

 Â Â Â  Debug mode is using __FILE__/__LINE__ to show where the assertion 
took place. So assertion looks like this:

/home/fdt/dev/gcc/build/x86_64-pc-linux-gnu/libstdc++-v3/include/debug/deque:175:
Error: function requires a valid iterator range [__first, __last).

 Â Â Â  But IMHO a smarter information would be to provide the file:line in 
the source code that generated this assertion so that users could more 
easily go to the faulty code.

 Â Â Â  So I am looking for __FILE__/__LINE__ equivalents pointing to the 
first non-system source file. Has any such request already be made ? Do 
you think it would worth a request to gcc guys ?
