Hi Pavel,

I'll reply to you first and then Akim.  It's easier to keep my mind straight
that way :)

This does work as you <Pavel> hoped.

Not quite (see below for the value of srcdir)

The make shipped with QNX is supposed to be GNU Make 3.74

I know I tried to compile make on the platform for 3.76 and did not succeed
so I am suspicious of patches not put back to the make code.

I hope so as I just noticed the value for srcdir in the Makefile is:

srcdir = //1/tmp/autoconf/. . .

Yes there are 3 dots, space separated in srcdir.

Where do I need to go to look for what creates this?

srcdir is //1/tmp/autoconf
pwd is /tmp/autoconf
cd srcdir && pwd is //1/tmp/autoconf 

So the line fails as they are not equal!

As I said earlier this box is our torture test of building now it will
be for autoconf too :)
