Dear all,

I'd need to compute the absolute path of srcdir in a portable way (it's
okay if it includes symlinks).

Couldn't you use the provided $abs_srcdir?

I was actually not aware that this variable was there but it seems it
gets replaced by the dirname of the .in file where it gets substituded,
whihc I find very odd actually. So if the software is in, say,

and the template file is in subdirectory foo of the tree, then when I
run configure, what I see in the file produced from the template is
/home/me/src/software/foo which is not quite what I expect.

It sounds like you want $abs_top_srcdir
