I accidentally deleted my D folder containing the compiler and 
other things. (It as a weird issue where I was trying to add a 
command to an app and because the %1 parameter didn't have quotes 
I guess it deleted the D folder as it shortened it to D) I had a 
backup and didn't change anything since then except for updating 
the compilers. Still had the same visual D version.

So I copied it over and updated dmd with visual D. Everything 
worked fine that day and I messed with the code several times. 
Woke up and wanted to make a simple change and code would not 
compile. The changes were insignificant. It gave me that error 
and when I added that switch then I got one about 
pragma(crt_constuctor) needing extern(C). Anyways, tried adding 
the extern(C) in the code but it wouldn't accept the changes.

BUT I just tried to compile it again and no issues.

Probably drive corruption issues or possibly some type of caching 
issue.

But I was able to make changes now and compile it like it should 
work.

E.g., it's possible that when I copied over the old D directory 
that it had an old compiler(I think it was from '22). I did 
update with visual D but maybe there was caching going on that 
was causing the conflict.

In any case everything seems to be back to normal. I really 
didn't do much to fix anything so it was probably all caused by 
deleting that D folder accidentally.
