[Bug ada/20822] New: makeinfo cannot process gnat_ugn_unw.texi

[rolf dot ebert dot gcc at gmx dot de]

when bootstrapping on Windows (mingw/msys) the documentation is not generated.  
Makeinfo stops with the complaint:

$ cat -v make.err 
doc/gnat_ugn_unw.texi:92: Unknown index `fn' and/or `cp^M' in @synindex.
./doc/gnat_ugn_unw.texi:11211: Cross reference to nonexistent node 
`Alternative^M File Naming Schemes'.

See the CR characters after cp and after Alternative.

I suppose it is a similar problem as the ones that get fixed by http://gcc.gnu.
org/ml/gcc-patches/2005-03/msg02615.html

a simple workaround for finishing bootstrap is to use make -k and simply do 
without the doc.
