Is this for bootstrap-only? ie: You can build once with the locally
generated (a) and then immediately rebuild the package using the
compiler in the just-built package? That can probably get an
exception from the FPC using the bootstrap guidelines fairly easily.
If the EPEL branches will always have to have step (a) pregenerated
then the outlook is a lot more grim but we can look at that if we
have to.
The library is for computing special six-dimensional integrals, for
which there are many possible ways to reach the wanted result using
recursion relations. The compiler has some heuristics to determine what
is the shortest path, and generates the code that implements this path.
So, the compiler isn't bootstrap-only, but given the above the
sources generated with the same configure flags should end up to be
equivalent. Upstream releases only stable tarballs of the generated
sources that are aimed for end users. The compiler doesn't have
these kind of stable releases, it's just available in a VCS.
