win32utils devel - Apr 2012 - RbConfig and CPPOUTFILE

Hi,

For some reason with my version of Ruby built with MSVC++ 10 the
RbConfig::CONFIG[''CPPOUTFILE''] value is set to "-P".
Shouldn''t it be
set to an actual file? With mingw it''s set to "-o conftest.i"

I guess I was expecting something like "/Fo conftest.i".

I ran into this with mkmf-lite if you''re curious, since I was using
the result of CPPOUTFILE to help create a build command. Or am I
misusing this?

Regards,

Dan

Ok, I think I got a bit confused there. MS just defaults to using the
input file name + ".i" with the -P option, so I guess it''s
why it''s
set like that.

Although, now I''m wondering why CPPOUTFILE is creating a .i file for
gcc, since that''s typically used for preprocessed files and not
executables, right?
