make error in base on Solaris

[Riccardo Mottola]

Hi,

after several months, I attempt an update on Solaris. It used to work!

I get a very strange make issue:

checking if we should install gdomap as setuid... no
checking for the version of gnustep-base we are compiling... 1.27.0
configure: creating ./config.status
config.status: creating config.mak
/bin/sh: test: unknown operator -nt
gmake: *** [Makefile.postamble:105: base.make] Error 1


and if I issue make again, I get:

bash-4.3$ gmake
This is gnustep-make 2.7.0. Type 'gmake print-gnustep-make-help' for help.
Running in gnustep-make version 2 strict mode.
/bin/sh: test: unknown operator -nt
gmake: *** [Makefile.postamble:105: base.make] Error 1

This is not very helpful... somewhere I suppose we are using a parameter 
that the sh is not liking, I suppose?
"sh" is not bash on solaris.

But where?

Do you know a trick to "force" using bash perhaps?
