Bug#533817: muparser: FTBFS on Debian GNU/Hurd [Patch]

[Gudjon I. Gudjonsson]

Hi Barry
    Ingo and Francesco have upgraded the build system. 
$ build/autoconf/acregen.sh works now.
Can you please test if it works. I have made an unofficial Debian package out 
of the svn version. I will make a patch if it works.

I am not so optimistic because I didn't find any
*-*-gnu*
pattern in any of the build scripts and neither in the config.sub or 
config.guess files. Do you know how this pattern is generated in general in 
gnu/hurd?

Cheers
Gudjon
