Hi, Team,

I tried to compile wiringpi-3.16 with GCC 15 and encountered the below error.

[Compile] wiringPiSPI.c
wiringPi.c: In function 'wiringPiGlobalMemoryAccess':
wiringPi.c:3363:5: error: too many arguments to function 'GetRP1Memory'; expected 0, have 2
 3363 |     GetRP1Memory(pciemem_RP1, sizeof(pciemem_RP1));
      |     ^~~~~~~~~~~~ ~~~~~~~~~~~
wiringPi.c:3329:6: note: declared here
 3329 | void GetRP1Memory() {
      |      ^~~~~~~~~~~~

But the compilation works if using GCC 14.

I find that the issue might comes from some behavior change on function signature specifies no argument.

• Compiling with GCC 15 gives error too many arguments to function verilogaparse Qucs/ADMS#115 (comment)

It seems that either improve the function to explicitly specify function signatures for wiringPiGlobalMemoryAccess() (and an additional function call change),
or compiling with -std=gnu17 in CFLAGS option in the makefile.

Can WiringPi team help improve the code and release a new version to make the compilation work for newer GCC?
(I prefer to download from tagged / released pages rather than building from the master branch 😅)

Best Regards.
