Compiling DMD with C++11

[Andre Artus]

I see there is quite a lot of code commented out with '#if 0', 
most of which looks like testing code. Unit tests in D is one of 
the 'killer' features. THE killer D feature for me is 'scope'.

I bring this up because I see

extern "C" longdouble strtold(const char *p,char **endp);
//strtold.c(583, 23):

is in one of those blocks. If 'strtold' had to change names who 
would be affected by it?
