Broken sed cause build problems
The configure script uses sed
to amongst other things generate the root Makefile.
It has turned out that some versions of sed (in the 4.0.X series it seems) don't properly support \n within the replacement string for the 'c' command.
Starting Dec 5 2005, the /c switch is no longer used by the configue script for sed, thus this whole page should no longer apply.
sed 4.1.2 and later are known to do right. sed version 3 also works fine.
