The test program works fine when compiled with gcc 2.95.3 for Linux/x86.
So, only BeOS and Haiku are affected.

It is not a big problem. Causes one test failure only. But some programs
(e.g. editors which watch the status of files being currently edited) will
not work optimally if ctimes are nonexistent.

Thanks, I'll try this.

Thanks for explaining. Indeed, /boot/common appears to be the equivalent
of /usr/local on other Unix systems - which is the default $prefix for
configure.
