cdecl99-1.3 bash-5 hotfix

Turns out that prior to release the package was not tested on any
systems where /bin/sh is bash-5, and the configure script hits a
parser bug in this shell regarding for loops in case statements.

A workaround is to set CONFIG_SHELL environment variable to some
other shell without this bug.  But if that's not possible, this
patch can be applied to avoid the bug.

+
+The configure script included with the cdecl99-1.3 release fails on
+bash-5 due to a parser bug in this shell.  On affected systems, a
+message similar to the following may be seen when running configure:
+
+  ./configure: line 6631: syntax error near unexpected token `do'
+  ./configure: line 6631: `do'
+
+You can work around the problem by setting the CONFIG_SHELL environment
+variable to some other shell before running configure; otherwise you can
+apply this patch file with a command such as:
+
+  % cd cdecl99-1.3
+  % patch -p1 <cdecl99-1.3-bash5-fix.patch
