Bug#78990: Cannot compile gnumach because of asm/string.h

[Ognyan Kulev]

Package: gnumach
Version: 1.2-2

Trying to compile gnumach on Linux, I do

apt-get install gcc-i386-gnu mig-i386-gnu
apt-get source gnumach
cd gnumach-1.2
export PATH=/usr/i386-gnu/bin:$PATH     # Is it needed really?
dpkg-buildpackage -ahurd-i386

and after cleaning, compiling, etc it stops:

I look at string.h, but asm syntax of GCC is too cryptic for me ;-)
