The POSIX / Bourne -comformant equality comparison is '='. 

e.g.

$ ./heirloom-sh/sh -c ' [ a == b ] || echo x'
./heirloom-sh/sh: test: unknown operator ==
zsh: exit 1     ./heirloom-sh/sh -c ' [ a == b ] || echo x'

Interesting that Solaris /bin/sh did not fail there...

Hmm, gen-version-script doesn't have shebang... it is run like:

sh $(srcdir)/$(lib)/gen-version-script.sh $< $(libnotmuch_modules) > $@

in lib/Makefile.local -- taking sh fron PATH.
