This is just bad code; using an older compiler as an escape hatch is
not a good idea.
The solution is to put correct function prototypes and correct headers
in the problematic source files.

I have previously touched this package (netcdf), and the issue here is
we have enabled -Werror=incompatible-pointer-types on GCC 14.
If you look at the Debian logs, the same diagnostics are there, but at
the warning level.
This is because NetCDF assumes implicit casts of pointers are
acceptable (this is no longer true with GGC 14).
The solution would be either patch the code to have consistent pointer
types or downgrade the error to a warning using
-Wno-error=incompatible-pointer-types.
