描述

Foremost in this is 32-bit Android, which is broken in amazing ways.

MinGW64-W32 is rumoured to support it, however, so we should define it for that platform.

We should ideally implement this with a combination of platform detection, version detection, and compiling code with -D_FILE_OFFSET_BITS=64 and seeing what the size of the types being used is.

研究方向
Review the linked PR #2996 for context on the buggy platforms. Examine Meson's platform detection logic in mesonbuild/compilers/ and environment.py. Implement a combination of os detection (e.g., Android), version checks, and compile time tests to conditionally define D FILE OFFSET BITS=64. Consider testing on a 32 bit Android emulator or using cross compilation.
