[ECOS] FW: "warning: type qualifiers ignored on function return type"

[ECOS] FW: "warning: type qualifiers ignored on function return type"

[Gary Stebbins]

The error "warning: type qualifiers ignored on function return type"
began occurring when I upgraded from gcc 2.95.2 to 3.0.1 (Platform:
Cygwin on Windows 2000). This was with eCos 1.3.1. I downloaded the
latest eCos files and tried again, with the same results. The line in
MyFile.c where the error occurs is "include <string>". 

Has anyone else run into this? Is this a compiler problem, or a eCos
source problem (or my problem)?

Thanks.

You don't get warnings when you use the recommended compiler.
You do get warnings when you use some other compiler.

I guess that makes it your problem!

I thought I was following directions... What should I be using?

From "Building the ARM THUMB development tools for Windows",
http://sources.redhat.com/ecos/tools/win-thumb-elf.html:

GNU Compiler Collection
The GNU Compiler Collection web site contains plenty of information
about installing and using GCC. Unfortunately the most recent official
release (GCC 2.95.2) is not capable of supporting eCos for ARM THUMB. A
snapshot of the GCC development sources should be used to obtain the
most up-to-date compiler with new features and bug fixes.

You don't get warnings when you use the recommended compiler. You do get

My humble apologies - I thought eCos recommended specific versions
of compilers, but they clearly don't. I must either be confusing it
with some other project or going out of my mind.

I'll leave that to someone who has a clue what they're talking about!
