Masaharu,
This is just a simple example. Our code does not include
<bits/types.h> directly. A quick grep of /usr/include shows that
<bits/types.h> is directly #included in no fewer than 32 other header
files in /usr/include. It is difficult to avoid it totally.
It seems to me that this problem needs some attention.
