Same thought I had about comments --- open with a pipe through m4
before parsing.

I've another thought, too.

Before Rolf came over to lfs chat selling his OGDL, I was using Lua
for my spec files. At first, having accepted and heavily used the
rpm feature of being able to interpolate %{name}, %{version}, and
%{release} into subsequent variable defines (commonly the Source:,
occasionally in %prep), I was looking for some way to get the same
effect with Lua. After searching a while I found it. Then I decided
I didn't want it.

The proliferation of these little convenience features comes with a
cost; reading a complex rpm spec file is a real chore. Try and
figure out what commands rpm will issue out of %build when it's
doing glibc.

So I decided that rather than having automatic variable
interpolation to e.g. let me update the version of a package without
having to edit it in multiple places, I'd just use global
search-and-replace. Since I use a separate spec file for each
package, this works just fine.
