Hello,

etags doesn't recognize a Fortran 90 function or subroutine if this is
declared recursive. I've created a patch for etags.c (version included
in emacs 23.1) that fixes the problem. As I'm not familiar with the
etags source code, I'm not sure if I did it the way it should be
done. For me the patch works and I have not noticed any side effects
so far, please check if this makes sense to you.

Example on reproducing the problem: For the included file 'foo.f90'
etags will produce:

TAGS:
foo.f90,48
subroutine sub(1,0
integer function func(5,50

As you see, some functions and subroutines were missed.

The patched version will produce:
TAGS:
subroutine sub(1,0
integer function func(5,50
recursive subroutine rsub(12,127
recursive integer function rfunc(16,189
recursive function rfunc2(22,278

This included all functions and subroutines.

Patch 'emacs-23.1-etags.patch' included (to be applied in
emacs-23.1/lib-src/)


Kind Regards

Kester
