dmd -o- -map prevents creation of map file?

[Pierre Rouleau]

Hi all,

dmd 2.047 help states that the -map option switch "generate linker .map 
file".

But when compiling a single (stand-alone) source file, dmd seems to 
generate the .map file even if the -map switch is not present.  Is this 
wanted? Should it not simply generate the .map file only when the -map 
option is present on the command line?
