comparison dep/toml11/toml/version.hpp @ 318:3b355fa948c7
config: use TOML instead of INI
unfortunately, INI is not enough, and causes some paths including
semicolons to break with our current storage of the library folders.
so, I decided to switch to TOML which does support real arrays...

| 10 // Since MSVC does not define `__cplusplus` correctly unless you pass | |
| 11 // `/Zc:__cplusplus` when compiling, the workaround macros are added. | |
| 12 // Those enables you to define version manually or to use MSVC specific | |
| 13 // version macro automatically. | |
| 14 // | |
| 15 // The value of `__cplusplus` macro is defined in the C++ standard spec, but | |
| 16 // MSVC ignores the value, maybe because of backward compatibility. Instead, | |
| 17 // MSVC defines _MSVC_LANG that has the same value as __cplusplus defined in | |
| 18 // the C++ standard. First we check the manual version definition, and then | |
| 19 // we check if _MSVC_LANG is defined. If neither, use normal `__cplusplus`. | |
