------------------------------------------------------------------------------------

Fixing that case statement allowed my configure to proceed further.... however I then encountered another problem:

checking for user-specified Apache 2.4 apxs name/location... "/usr/local/apache/bin/apxs"
checking to see if Apache 2.4 apxs was located... /usr/local/apache/bin/apxs
checking for apr-1-config... ./configure: line 21124: -q: command not found
no
configure: error: Unable to locate apr-1-config, may need --with-apr1 option.


If I further modify the configure script, replacing:
  21092     # If we haven't done this work already for Apache 2.2
  21093     if test "$WANT_APACHE_22" != "yes" ; then
  21094         # APR1 settings
with:
  21092     # If we haven't done this work already for Apache 2.2
  21093     if test "$WANT_APACHE_24" != "yes" ; then
  21094         # APR1 settings

I've no idea whether this is really ok, but doing so results in my configure completing, although I get scary looking warning:
==================================================================
WARNING: You have chosen to compile Apache-2.4 modules with a different
         compiler than the one used to compile Apache.

    Current compiler:      gcc
   Apache's compiler:      gcc -std=gnu99

This could cause problems.
==================================================================

Do you know if this is really likely to be a problem? If so, any idea how I solve it?

I can then run the make which results in mod_shib_24.so , which I can successfully include in my Apache config with the LoadModule line. I haven't got as far as trying to configure the Apache to actually use it yet though - so don't know whether it really functions.
