Fails to build on linux with gcc-14

[Shoegzer]

As the title implies, this core fails to build with gcc-14. The following error is generated:

daphne/daphne-1.0-src/vldp2/vldp/vldp_internal.c:852:31: error: implicit declaration of function ‘fileno’ [-Wimplicit-function-declaration]
  852 |                         fstat(fileno(F), &filestats);   // get stats for file to get file length
      |                               ^~~~~~

It builds successfuly with earlier compilers such as gcc-13

@hunterk any thoughts here?

Update: This seems to be coming from internal changes related to gcc-14, as encountered and discussed here and here.
