hi samuel,

i have suitably old versions of the mesasdk for 7624 on osx.
maybe someone lese has a linux version of mesasdk_20150827.

alternatively run the models on the current public release r01398 
with a current version of the mesasdk. the inlists and other tools
for this paper are at http://cococubed.asu.edu/mesa_market/inlists.html

They're mostly caused by variables in conditional blocks where the compiler is worried that MESA hasn't given them a value, even though MESA does give them an appropriate value if it uses those variable.  Initializing them to 0 (or whatever) at the beginning of the relevant subroutines/functions should work (without affecting MESA's results).  You can also look at more recent versions of MESA to see how the main codebase has been changed to satisfy these requirements for newer versions of the compiler.
