glibc CVS doesn't compile on ARM

[Robert Schwebel <robert at schwebel dot de>]

Hi, 

[Please Cc: answers to me, as I'm not subscribed to the libc-alpha list.
Thanks.]

I have recently tried CVS-glibc with an 2.95.3 ARM toolchain (see
http://www.pengutronix.de/software/dnp/build-toolchain-ptx1 for details
about how such a toolchain can be built), and it breaks. Background was
that glibc-2.2.5 can currently also not be built for ARM, so I wanted to
test the latest stuff. 

Here's the bug report:
