In 32-bit AIX 7.2, fstat delivers the low-order 32 bits of the file's 
timestamp, instead of failing with errno == EOVERFLOW as it should. 
Since 'grep' doesn't use the timestamp it goes ahead and does the right 
thing.

Perhaps Manjaro 17 (2017) does something similar. As I understand 
things, though, it uses the Linux 4.9 kernel, which was supported only 
through January of this year. Since Manjaro 17 was the last Manjaro 
release to support 32-bit architectures I suggest not worrying about it 
as a 32-bit porting target.

PS. Wikipedia says AIX 7.1 support ends April 30, so it looks like we 
can stop worrying about AIX 7.1 soon. AIX 7.2 and 7.3 are still going 
strong, though.
