The N64 <stdlib.h> stub declares neither. MinGW's other CRT headers leak them; a strict host GCC (Linux/macOS, -std=gnu11) does not, so getenv()'s 64-bit char* return is assumed int and truncated -> configGetFrameDump (GE_PCDUMP path) dereferenced a low-32 pointer and segfaulted. Add K&R decls: pc_protos.h (D38 mechanism -> game TUs via <ultra64.h>) and the port/shim/stdlib.h non-Windows branch (-> port TUs that #include <stdlib.h>). K&R form stays compatible with the real prototypes; malloc/ calloc/free are already covered elsewhere so not repeated.

* 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).
