optionsoverlay.c called atoi and lround through implicit int declarations (GE's stub stdlib.h/math.h shadow the CRT, D324 class); atoi joins the other K&R decls in port/shim/stdlib.h, lround gets a local prototype. Windows + Linux builds clean of both warnings. GE_INPUTSCRIPT gains ZHOLD/ZREL (sustained fire) for automatic-weapon audio repros. D207/D241: headless burst-fire at 60 vs 30 fps with the alarm forced logged zero voice drops at both caps; owed a real-play capture. Golden gate 3/3.

/*

* PC port shim for <stdlib.h>.
|
|
*
|
|
* The N64 decomp ships include/stdlib.h (a libc stub: lldiv_t/ldiv_t typedefs
|
|
* + a couple of prototypes). C game code gets it, exactly as on the console.
|
|
*
|
|
* In C++ TUs (fast3d) it must NOT be used: MinGW's own headers pull in the
|
|
* host <stdlib.h> through their include chains (sec_api/stdlib_s.h does
|
|
* `#include <stdlib.h>`, which resolves to the N64 header via -I), and the
|
|
* lldiv_t/ldiv_t typedefs then conflict with the host's. The shim routes C++
|
|
* TUs to the host header by absolute path (generated hoststdlib.h, same
|
|
* trick as port/shim/string.h — see docs/internals.md §11 D12).
|
|
*
|
|
* Inert in the N64 build (port/shim is not on its include path).
