error: narrowing conversion in btSerializer.cpp (c++11, ARM)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile for ARM targets using c++11.

What is the expected output? What do you see instead?

Fails to compile since chars are unsigned on the arm platform.

What version of the product are you using? On what operating system?

2.80 r2528

Please provide any additional information below.

Same as issue 604, but for ARM targets.

Attached patch does an explicit cast to (char) for all the negative values.

It is an autogenerated file, so the casts are inconvenient.

Can you try making the array explicitly 'signed char'?

signed char sBulletDNAstr[]= {

By the way, what compiler version/platform/flags did you use to enable C++11?

Is should be fixed in latest trunk, including the auto-generation code:

Can you try it?

Thanks for the report!
