That's true, but
a) afaik it's only supported on Mac OS X
b) our Stabs writer does not support those extensions (I initially  
tried using Stabs on Mac OS X 64 bit because back then DWARF support  
in FPC was not very good, but changing the Stabs writer seemed more  
work than improving the DWARF support)
