[wdiff-bugs] Bug#583000: bashism in configure script makes build to fail

[Santiago Vila]

Hello.

I received this report from the Debian bug system.

It seems the root of the problem is a bashism in the configure script.
Patch follows.

BTW: Adding the letter "x" reminds me of MS-DOS .BAT programming,
where such trick was necessary. Should "$with_termcap" = "auto" not
work well enough, even if $with_termcap is empty?

Subject: Bug#583000: wdiff: FTBFS: ld: cannot find -lauto

Source: wdiff
Version: 0.6.1-1
Severity: serious
Tags: squeeze sid
User: address@hidden
Usertags: qa-ftbfs-20100524 qa-ftbfs
Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part:
> gcc  -g -Wall -O2   -o wdiff wdiff.o readpipe.o writepipe.o ../lib/libgnu.a  
> -lauto 
> /usr/bin/ld: cannot find -lauto
> collect2: ld returned 1 exit status

The full build log is available from:
   http://people.debian.org/~lucas/logs/2010/05/24/wdiff_0.6.1-1_lsid64.buildlog

A list of current common problems and possible solutions is available at 
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

About the archive rebuild: The rebuild was done on about 50 AMD64 nodes
of the Grid'5000 platform, using a clean chroot.  Internet was not
accessible from the build systems.
