Anybody seen this? Any ideas what I should do?

Thanks in advance,

What platform are you on? I'm guessing a 32-bit linux?

There should probably be stdio.h files in the following subdirectories of the prefix:

arm-none-eabi/include/sys/stdio.h
arm-none-eabi-include/c++/4.6.1/tr1/stdio.h
arm-none-eabi/include/stdio.h

Yes, the files are there, but wouldn't you expect gcc to pick them up
automatically, e.g. after an ``#include <stdio.h>''?

Yep, I suppose it's for some reason not looking in the correct paths.

certainly something like this should work:

test.c:

cat test.c

#include <stdio.h>

void main( void )
{
    printf("Hello world!\n");
}

then:

arm-none-eabi-gcc -v -c test.c

I get the following output:

It's not going to link without some missing functions, an entry point, and at least stubs for functions that would normally be taken care of by an OS, but it should at least compile as above.
