Yes, that issue is somewhere between Windows and SCons. More details at
https://bitbucket.org/scons/scons/wiki/LongCmdLinesOnWin32 , as I wrote above.

> use the shortest path possible for the repo and install location (iirc I used e:\p\ and e:\i\ respectively)
I assume that would be acceptable not for all users (Linux users don't have
such restrictions). But Mesa builds using MinGW-W64 fails even from e:\p\
directory, because 'ar' utility receive command line with about 12,355 symbols
(see attachment above), while Windows limit seems to be 10,000 symbols.

As I understood your sample relates to Mesa builds using LLVM, while my error
report relates to builds using MinGW-W64.
