https://dlang.org/dmd-windows.html#switches

specifies that DMD may be passed a file on the command line that 
contains compiler arguments and switches. This may be freely 
combined with regular command line arguments if you so wish.

So, you could have a file called 'versions' containing this:

# Setting 'Compress' version
-version=Compress
# Optionally set other versions
#-version=Foo
#-version=Bar

and feed it to dmd like so:

     dmd -w -wi -g @versions -main foo.d
