It seems that the compilation under Cygwin is more complicated than
expected.
Thank you for your explanation, Warren.

My wild guess based on no personal experience with BLAST+ is that
there is some linkage error here. I'd have to try it myself (not
interested) or examine the config.log file (still not interested) to
figure out if this guess is correct.
I'd bet there are more Cygwin-using BLAST+ users on the BLAST+ mailing
list than on the Cygwin list, so you'd have a better chance of getting
a solution by sending the config.log file to that list than continuing
to pursue this problem here.
Instead of trying to start with RPM, I'd recommend figuring out how to
build BLAST+ to build from source first. You need that experience to
help you build binary packages.
I think you'll have an easier time learning to build a native Cygwin
package than trying to get the .src.rpm file to rebuild on Cygwin:
http://cygwin.com/setup.html
That page gives several methods for building Cygwin packages. I'd
recommend going with the Cygport option. Cygport does fewer things
than RPM, so building .cygport files is easier than building RPM .spec
files. (In Cygwin, much of the rest of what RPM does lives in
setup.exe and cygcheck.exe.)
I doubt there's enough value in the existing BLAST+ .spec file to make
it an easier path for you than building a .cygport file from scratch.
Then what is [the rpm package] for?
It is for people who wish to build a secondary packaging system on top
of Cygwin's native system.
It doesn't magically port Linux RPM packages over for you. You still
have to do that work yourself. And, you have to do that work without
having the benefit of an ecosystem of existing RPM binary packages,
upon which that BLAST+ .spec file probably depends.
