[Groff] [groff] table of contents and hyperlinks

[bertrand]

I am using groff with ms package to generate pdf. I use the .XN macro
for my titles, for ex:
.NH 2
.XN My Title

and the .TC macro to generate my table of contents at the very end of
the document. In the pdf doc, I have the left side pane and the links
work fine. However, the table of content is well generated, but there
is no links, only plain text.

I am using groff 1.21, with the following commands:
groff -pt -m ms -m pdfmark -m spdf -Tps mydoc.ms > mydoc.ps
ps2pdf mydoc.ps

Am I missing something ?
