Subject: Ping: [PATCH] Add DWARF constant for Borland fastcall calling  
convention

Hello,

This is basically a ping for http://gcc.gnu.org/ml/gcc-patches/2009-04/msg00301.html

I've however added a comment describing this calling convention. This  
patch is all but accepted for gdb, but since gdb imports dwarf2.h from  
gcc, it should really be applied here too.

I don't have a copyright assignment on file yet for gcc (I've  
requested one), but I hope this can be checked in under the "tiny  
change" rule.

Thanks,


Jonas
