What do you worry about? A few bytes in statically linked program? A few
bytes for dynamically linked programs? In both cases, the change should
be initialisation of static_buf at the time of first use, making it go
to BSS by default.

The change just adds/keeps an undocumented, arbitrary limit in libc.
This is a *path name*, so it should be limited by the name of path names
and nothing else.
