gcc 10 incompatibility still present in IGAMX2D call in pstrsen.f and pstrord.f

[traversaro]

First of all, thanks for the work on scalapack and sorry if the issue is not relevant.

I am trying to compile scalapack 2.2.0 with gcc 10, and I am getting error of type:

In theory all the problems of this kind should have been fixed by #23, but on that specific file we are still getting them. Notice that the same error was also reported by the Homebrew CI, see https://github.com/Homebrew/homebrew-core/pull/94420/files#diff-e45b9bfcc61ceafda0d6200c3c06dec48c0da5a6259d8346659d3fe822b0ae0bL35 .

This is fixed in #51, which I think will be merged soon

[traversaro]

Thanks a lot, I had missed that PR.

Hi @traversaro. We merged #51. Should I close issue #55 ?

Ok for me, thanks!
