g95 install failed on Mac OS Sierra 10.12.1

[AliceBreeveld]

I have tried cleaning, uninstalling, removing any gfortran from my computer and any g95 references. I repeatedly get this:

Hi, in the hope that the following is useful...

This ticket is now six months old. And there are three new tickets reporting the same problem, #54108, #54109 & #54155.

The problem seems to be simply that two comments at the beginning of the file libf95/math/x87.S which start with "##" are being mis-intrepretted somehow and producing "unexpected token at start of statement" errors.

The two lines are:

 ## Some of the code here is transliterated from the x87 glibc code
 ## originally written by J.T. Conklin and Ulrich Drepper.

If one simply encloses these in /* ... */ the problem (appears) to be solved, i.e.

/*
 ## Some of the code here is transliterated from the x87 glibc code
 ## originally written by J.T. Conklin and Ulrich Drepper.
*/

I can provide the modified Portfile and the patch file which implements this fix.

Best regards

John Pritchard

Actually, this particular ticket seems to be slightly different from the other three ( #54108, #54109 & #54155 ) as this one is about failure during configure, whereas the other three are about failure during compilation.

My solution above is for the case of failure during compilation.

I suspect though (since we are at 10.12.4) that there is no longer an issue during configuration, just the problem during compilation.

Cheers John
