I posted this to gnu.g++.help, but that is not a very high traffic newsgroup.
The code is a stripped down version of what was produced by KDevelop using
the Automake Manager.
Sorry about the big code dump. I tried to get it down to the minimum
required to demonstrate the problem. On the following I run
aclocal
autoheader
autoconf
automake -a -c --gnits
./configure
make
with the results shown at the end of the code listing. The problem seems to
be related to my using static const class members. Other similarly
configured programs work OK. Can someone tell me what I'm doing wrong
here?
