Hmm, I didn't see this problem, but see below.

Hi,
finally I didn't need the names containing a '$' at all. :-)
I was creating autoconf/automake/libtool files for a java / gcj project
and tried to complile some class files containing nested classes. These
files have names similar to "xyz$abc.class".
Thas's how I discovered the problem with automake and filenames containing
a '$'. I fixed the problem and discovered linkage problems with the
compiled *.class files. The solution was to build a jar archive containing
the *.class files and to compile this archive. Nevertheless I thought my
patch might be usefull in some cases. That's, why I submitted the patch.
