Previous versions of gcc have had limits.h in /usr/lib/gcc

/usr/lib/gcc/i486-linux-gnu/4.2/include/limits.h
/usr/lib/gcc/i486-linux-gnu/4.3/include-fixed/limits.h

but 4.3.3 does not. So the include_next <limits.h> at the end of
packages/isoinfra/current/include/limits.h fails.

Some more bits of info would be useful, to know how (or if!) this should be
fixed. I say "if" in case this is a mistake in that compiler and trying to
support it is too hard. I note also that the build problem is in JFFS2 which
munges include paths specially by adding " -nostdinc -iwithprefix include" for
synth. Any fix is likely to be in JFFS2, not isoinfra.

1) Can you tell me where limits.h actually is now?

2) Can you provide the output of compiling a normal C file with gcc 4.3.3 but
adding -v.

3) Can you repeat the compile of fs-ecos.c exactly as ecos builds it, but
adding -v.

4) If you could build fs-ecos.c using gcc 4.3 and -v as well that would save me
some time, assuming it's easy for you to try. If not, don't worry about it.

5) And can you just explicitly confirm that 4.3 worked.

When you compile with -v, it will provide extra info about the include path,
which will be useful.

Lets start with a native program compiled with gcc:

#include <stdio.h>
#include <limits.h>

int main(const int argc, const char * argv[])
{
  printf("CHAR_MAX = %d\n", CHAR_MAX);
  return 0;
}

I also tried compiling fs-ecos.c with gcc-4.[012] and they work. The only
version which breaks is 4.3

Fix compilation

This patch appears to fix the compilation.

I've not run the test cases yet, or tried other versions of gcc. So this is not
yet ready for committing.

I ran /install/tests/fs/jffs2/current/tests/jffs2_[12] and they pass.
jffs2_3 fails, but it also fails with gcc-4.2. 

I tried gcc-4.2 and that will compile O.K. with my patch.

Hi Andrew

(In reply to comment #5)

> Should i commit this patch?

The patch is non-invasive in the sense that it only affects compilation of the
eCos JFFS2 package for the synthetic target which is currently broken. I have
verified that the patch does not break compilation with gcc-3.2 and gcc-4.1.2.
No-one has objected to the patch, so I suggest you proceed with committing it.
Thanks.
