1. It's highly recommended to use STLport instead of STL from eVC++, if
you are building using eVC++.
2. This warning can be safely ignored

You need to apply patch to your eVC++, please follow these guidelines:

These warnings can be safely ignored.

I don't know what you're trying to run on what machine, but this message
clearly says there is mismatch of target platform of the binary and
actual platform.

Probably, you use incorrect SDK.

Note, in README there is a step for makefile.vc:

2. Run configuration script for ARM target.

that suggests only ARM platform is supported.

I've never used emulator with eVC++ 4.0 because it is x86 instead of
real ARM emulator. Project files are not prepared for emulator target.
So, I can't help you with using emulator with eVC++ 4.0.

I appologize if README file and instructions are not clear enough.
I will update it for GDAL 1.4.0 release.

Cheers
