Subject: Re: [OMPI devel] a bogus warning: undefined symbols not allowed in x86_64-pc-cygwin shared libraries

I'll have to look into that. It looks like with all my humble patches
it should compile and pass the tests successfully even if compiled
with -march=native -mtune=native -Ofast+ optimization, and all the
perks enabled. That is, if the missing headers will be made available.

No, I haven't been contacted by Mellanox nor by any respectful
organization mentioned on the OMPI membership list to support Open MPI
under Cygwin 32/64-bit. Even if I have a degree in Physics, invested a
personal fortune in my Quantitative..., in my second-third degree
studies in Switzerland, and have 20+ years of work experience in the
IT field, quite recently with the Brutus cluster, who would be willing
to look for a new hire nowadays?
