The conventional DOS path has a hard limit of 259 characters: 3 for the drive letter and immediate 
colon-slash, and 256 for the path itself. (If the null terminator is counted then it's 260 
characters, which is exactly the value of `PATH_MAX`.)

The simple solution is to move the toolchain to somewhere shallower, apparently.

The permanent solution to this problem would be using UNC paths. For example, instead of writing 
`C:\Windows`, you write `\\?\C:\Windows`. This makes use of a 64KiB buffer, but please note Windows 
NT uses UTF-16 paths, so the length limit of a path is 32767 UTF-16 code units.
