This analysis is probably correct. I'll try to check in a fix.

Rev. 101149 still fails in the same manner. And these warnings

are not too reassuring...

I'll try to set up a cygwin environment here. That will take a while.

Sorry, but this issue is not Cygwin specific at all: I think you
should setup also a GNU/Linux Kubuntu 8.04 system, on which there are
the *same* identical problems that occur on Cygwin. On K804
imagemagick is 6.3.7.

Ok, I will download a vbox image and set up ubuntu 8.04.

BTW the warnings seem to stem from some api change. I'll figure out some
solution for that also.

The main problem is that bootstrap fails because the 'logic' in configure.in looks wrong in any case, as pointed out by Ken.

If on Kubuntu 10.04 (the last Kubuntu) the bootstrap works, it happens _ONLY_ because the ImageMagick is more recent and, accidentally, has MagickExport.. defined.

I would fix this issue before installing other software.

Ciao,
Angelo.
