MinGW’s compiler (GCC 14.2.0) errors out compiling `synctex_parser.c`.
```
synctex_parser.c: In function '_synctex_updater_print_gz':
synctex_parser.c:8448:13: error: implicit declaration of function
'vasprintf'; did you mean 'vsprintf'?
8448 | if (vasprintf(&buffer, format, va) < 0) {
| ^~~~~~~~~
| vsprintf
```
`vasprintf` is a custom function (not the standard `vsprintf`) that’s
defined in the same translation unit a few lines above.
However its definition is wrapped within a `if defined(_MSC_VER)`
i.e. it’s only enabled when compiled with MSVC compiler. This fix
enables it also for MinGW compilers.
`vasprintf` is a function available on Linux and macOS but not in Windows. Instead of restricting it for MSVC and MinGW, enable it for all compilers using standard C library function `vsnprintf`.
UCRT64 is the newer MSYS2 environment compared to MINGW{32,64}. This
is the recommended default [1].
> If you are unsure, go with UCRT64.

works like a charm, would love to see it in master/melpa version |

same as CommanderAsdasd : works for me, would love to see it in master/melpa version |

Same here. It works for me, would love to see it in master/melpa version. |

Thanks @legends2k! Though it seems to cause a problem when double-clicking a word (using it with Org-noter)? |
