It makes separating things like version info from function hard.
The %else function is a minefield.
The %if statements around nearly every line in configure give you a hint
of the problem.
Autotools is not the last word in pretty language but it does warn when
you do platform specific stuff very well, and its a lot more flexible
than rpm.

These conditionals do not occur just done once if used in the spec.in
file though its worse, you need the same conditionals on each of
configure
files
install
Admittedly if we follow the current process of deprecating direct
platform based installs we can get the conditionals down to two places
in the spec.in file rather than 3.
I think having the conditionals set in one place is superior to 2 or 3
places. To do this you would template the rpm spec file.
