Bug#1075698: Patch to ygl package (fixing gcc-14 bug)

[Pablo Lucas Silva Santos <pablolucas890@gmail.com>]

Hi there,

I have worked on this Bug and learning about gcc-14 changes, I saw that 
the new version of gcc needs to declare implicit functions that was 
unnecessary on older version of gcc [1]. I'm attaching a patch with the 
solution and I'll add a tag for Bug, let me see if I help with something,

I'm just a beginner contributor and I'll try to learn more about 
packaging to maybe get this package to maintain.

Also, let me know if some DD like to be a sponsor for me, I'm 
contributing with debian translate team (l10-portuguease) and studing 
classes from Marcos Talau and Eriberto (Some names from packaging and 
bugs that we have on Brazil)

Kind regards,

Description: This patch add five new external declarations on fortran.c
file. It was unnecessary on older gcc version (13), but now, it isn't more
possible to call functions not declared [1]. I just adding the declarations
on file, I didn't study about the upstream project to see the better part
of the code to put it, however, the bug are fixed.
