Re: relocatable-prog : relocatable symbol not found

[Sylvain Beucler]

Hi,

I'd like some input about this issue.
I don't understand how gnulib-tool generates the Makefile.
In this case relocatable.c is added to EXTRA_libgnu_a_SOURCES but not
libgnu_a_SOURCES :/

(btw, now could be a good time to add FreeDink to 'users.txt' :))
