thunderbird configure issues?

[Richard PALO <richard.palo%free.fr@localhost>]

Wanting to advance a bit on solaris support for thunderbird[24esr]
in the continuation of the topic started concerning firefox and java on 
pkg-users%netbsd.org@localhost, I noticed the following during configure:

> checking for application to build... ../mail
> checking if app-specific confvars.sh exists... ./../mail/confvars.sh
> /tmp/subscript.ZQjw7a: line 109: ${enable_patsubst(calendar, -, _)+set}: bad 
> substitution
> /tmp/subscript.ZQjw7a: line 116: ${enable_patsubst(incomplete-external-linkage, 
> -, _)+set}: bad substitution
> /tmp/subscript.ZQjw7a: line 124: ${enable_patsubst(ldap, -, _)+set}: bad 
> substitution
> /tmp/subscript.ZQjw7a: line 129: 
> ${enable_patsubst(incomplete-toolkit-ldap-autocomplete, -, _)+set}: bad 
> substitution
> checking for gtk+-2.0 >= 2.10.0 gtk+-unix-print-2.0 glib-2.0 gobject-2.0 
> gdk-x11-2.0... yes

Can't seem to put my finger on where this is generated, but is it 
possibly an autoconf/m4 issue?

So far, I've only done the following:
