[Mingw-users] gcc as frontend for an assembler file

[Andre S. <ahm...@ca...>]

Hi,

I try to use gcc as an frontend to an assembler file. This works fine with
Linux/FreeBSD but seems to fail on MinGW.
If I type '$ gcc -c myfile.s -o myfile.o' on MinGW I get all kind of error
messages.

Can anyone advise me on this matter?

Kind regards,

Andre Steenveld.


Here is a source file followed by the error messages it generates.
(The source file comes from the backend of an compiler I would like to use
under windows.)
