error: expected declaration specifiers before 'ATTRIBUTE_RETURNS_NONNULL'

[Shaun Jackman]

I'm seeing a strange error when compiling gcc --with-sysroot. So far
I've successfully (I think) installed the linux headers and compiled
and installed binutils and glibc for this sysroot. I'm working on GCC
now.

libiberty.h:110:38: error: expected declaration specifiers before
'ATTRIBUTE_RETURNS_NONNULL'

The configure line is as follows. Any thoughts? Here's the gist of
four log files:
https://gist.github.com/sjackman/cdc4961f0d6751d7e1c0

config.log configure.log libiberty-config.log make.log

Cheers,
Shaun

Looks like binutils (?) is bringing its own slightly older version of
ansidecl.h, and sadly gcc puts that -I flag before the one that would let
it find its own ansidecl.h. Some workarounds could be (pick only one):
* download a more recent binutils (a snapshot if there is no release)
* replace the ansidecl.h installed by binutils by the one you can find in
the gcc sources
* temporarily rename the ansidecl.h installed by binutils

I opted for #3 `temporarily rename the ansidecl.h installed by
binutils`, and it worked nicely. Thanks for your help, Marc.
