Weird DWORD error

Chris Ponder

Hi,

I am stuck with a very strange error and was wondering if anyone can help. I have been given the task of updating a USB stack used in our firmware: elm-chan.org/.../00index_e.html

I downloaded the latest source, linked it in to the poroject in place of the previous version and am now getting an error from the line:

typedef unsigned long   DWORD;

Looking at the previous version of the code this line was:

typedef unsigned long   FFDWORD;

Sure enough, changing the name to anything except DWORD seems to work like a charm, but will require me to track down the rather large number of instances of DWORD and change them to something else. More importantly,

typedef unsigned long      DWORD;

should work!

I am using keil uVision V3.31 and am stuck using that version as the code doesn't compile correctly on later versions.

Does anyone have any ideas? Is this a Keil 3.31 bug, or have I just not set something correctly?

Any help is much appreciated.
