How to build changes made in "os" directory files?

[Lindenmaier, Goetz]

Hi,

The os_aix files are the implementation of the aix OS port.
AIX is an operating system by IBM

These files will be used if you build on AIX.

I would guess you build on linux.  In this case you need
to edit the os_linux files.

Best regards,
  Goetz.
