autoconf: exporting functions

Is there a way to export a shell function definition from configure.in
to configure?

I have something like:

function blabla {
}
...
blabla arg1 arg2 arg2

AC_ARG_WITH ...

...

in my configure.in

But then blabla gets stripped off by autoconf so I get 

./configure: line nnnn: blabla: command not found

Is there a AC command to export the the function, something like:

AC_EXPORT_SHELL_FUN("function blabla {
}")


Thanks
Petter
