Bug#1077247: Should mpich provide a mpic++.mpich symlink?

[Adrian Bunk]

Package: mpich
Version: 4.2.0-6
Severity: serious
Tags: ftbfs
X-Debbugs-Cc: Thibaut Paumard <thibaut at debian.org>
Control: affects -1 src:gyoto

gyoto does FTBFS on 32-bit, due to mpich being used there:
https://buildd.debian.org/status/logs.php?pkg=gyoto&ver=2.0.2-2

...
./configure: line 1938: /usr/bin/mpic++.mpich: No such file or directory
...


This is due to the following code in debian/rules:
  # Make sure we build with the right MPI implementation
  include /usr/share/mpi-default-dev/debian_defaults
  MPICXX := /usr/bin/mpic++.$(ARCH_DEFAULT_MPI_IMPL)
  export MPICXX


mpic++.openmpi does exist, which makes me wonder whether the
correct fix would be to add a
    mpic++.mpich -> mpicxx.mpich
symlink in the mpich package.
