After installing binutils-2.18.50.0.4, glibc-2.7-r1 failed with the folowing:

{standard input}: Assembler messages:
{standard input}:39: Error: suffix or operands invalid for `fnstsw'
make[2]: *** [/var/tmp/portage/sys-libs/glibc-2.7-r1/work/build-default-i686-pc-linux-gnu-nptl/math/ftestexcept.o] Error 1
make[2]: Leaving directory `/var/tmp/portage/sys-libs/glibc-2.7-r1/work/glibc-2.7/math'
make[1]: *** [math/others] Error 2
make[1]: Leaving directory `/var/tmp/portage/sys-libs/glibc-2.7-r1/work/glibc-2.7'
make: *** [all] Error 2
*
* ERROR: sys-libs/glibc-2.7-r1 failed.

Googling I found this:

http://www.nabble.com/The-Linux-binutils-2.18.50.0.4-is-released-td15360254.html

Where the above problem appears to be related to this from the article:

Quote:
Starting from the 2.18.50.0.4 release, the x86 assembler no longer
accepts

fnstsw %eax

fnstsw stores 16bit into %ax and the upper 16bit of %eax is unchanged.
Please use

fnstsw %ax


Are we filling bug reports on these interim binutils releases or just let it slide till it gets picked up as there is enough to do already?

I encountered the same problem.

This helped:

http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html

Add a patch to your overlay (glibc/files/2.7/...), and then it should compile fine, and even work fine (i compiled it at home and it did work so far).

Has this issue been resolved with binutils-2.18.50.0.5?

It's bug in glibc, not binutils.

I know it is but it is it was only noticed with the changed behaviour of binutils. The behaviour may have changed again.
