Minimo Build problems - ARM assembler troubles?

Hi folks,
I'm trying to build mimimo, with a view to making it work in a
friendly way on other Windows CE devices, primarily WinCE3.0 Handheld
PCs, and WinCE 4.x devices other than PocketPCs.

I'm having troubles with the build.  My system is WinXP SP2, and I'm
using EVC4 with Visual Studio 6 (SP5) for the native build stuff.

First off, I had problems with the client.mk makefile.  It didn't like
Windows-style "\" directory separators in MOZ_OBJDIR - changing to
c:/home/mozilla/arm-obj-dir solved that...

I'm now having problems with the ASM portions of the build. 
Basically, the include path seems to be causing me problems, and the
assembler directives seem to be being misinterpreted.

Quick snipped included below.  If anyone could help, it would be most
appreciated.  If I should provide more config details, please let me
know!

Thanks,
Nick.
