Today I've modified Igor's patch as follows:

1) The part of his patch which depends on libcolorer
is built as shared library (libcolorer_glue). The library
exports a single method which is used to get an array
of function pointers - these are methods from the library
that the editor calls.

2) The part of his patch which doesn't directly depend
on libcolorer remains in the editor source tree (only
C code). It exports a set of functions which the code
in libcolorer_glue needs to query to the editor, again
passed as an array of functions pointers.

3) The editor tries to dynamically load libcolorer_glue.so
and if it fails it fallbacks to the default syntax highlighting
code. Otherwise colorer is used.

These changes allow one to build MC with colorer support but
doesn't require libcolorer to be present on the target system.

I've made also some other changes - mainly related to the autoconf
stuff.

Since I am to tired to diff now I'll post patches tomorrow.
