Type and rank mismatch errors when compiling with gcc 10

[tomasstolker]

Hi @farhanferoz, thanks a lot for offering this great tool.

When compiling MultiNest with gcc version 10, I got the following errors about type and rank mismatches:

error.log

I could solve the issue by downgrading gcc version to 9.3.0 in which case the errors did not appear.

The solution I found is:
export FCFLAGS="-fallow-argument-mismatch"
export FFLAGS="-fallow-argument-mismatch"
this converts the type mismatch into a warning. You can also suppress that warning with:
export FCFLAGS="-w -fallow-argument-mismatch"
export FFLAGS="-w -fallow-argument-mismatch"

@tomasstolker I added a pull request to the original issue on the relevant repository JohannesBuchner/PyMultiNest#166

Cheers,
