Emacs has run on Solaris and AIX for decades, these platforms are stable 
and are supported by Oracle and IBM respectively, and there's very 
little trouble keeping Emacs working on these platforms.

And it's not just these two platforms. My bigger motivation for this 
particular change was that the old code violates a constraint specified 
by the C standard. Even though the old code works on GCC, Clang and 
MSVC, there's a reasonable chance it won't work on less-commonly-used 
compilers and there's little point to taking that risk when the fix is 
so simple.
