include file processing expert to look into this. I also asked if
there is some other compiler option we can apply [...]
The trick here is to specify include directory in a Unix-style form
pointing to the location of the source file. In this case, it would be:

  /INCLUDE="./modules"

With this command line switch, the compiler is able to process a path
relative to source file in '#include "../native.h"' directive.

The quotas around "./modules" are necessary and cannot be omitted.
Without quotas, the command line interpreted will interpret /modules
as a separate command line switch instead of a value of the /INCLUDE
switch.

I modified build_vms.com script so that it defines cc command as having
/INCLUDE switch above. I've attached modified script. It also fixes a
bug in cleaning/restoring [.bootstrap_vms] directory which I overlooked
in 2004 :-)

With modified build_vms.com and build.jam sent in e-mail, I was able to
build bootstrap jam which compiled all jam modules -- see below. I did
not have to modify build.jam to specify /INCLUDE switch because, when
executed from a script, the bootstrap jam "inherits" cc command
defined by the script.

Since I was using the 1.31.0 distribution which does not have the
[.modules]order.c module, I did not get to the link phase. However,
when I modified build.jam to remove order.c, I got the following
error:

$ MCR [.bootstrap_vms]jam0.exe -f x.jam --toolset=vmsdecc
...found 81 targets...
...updating 1 target...

    link    /EXECUTABLE=[.bin_vms]bjam.exe   /NOMAP /NODEBUG    ")
...failed [COMPILE.LINK] [.bin_vms]bjam.exe...
...failed updating 1 target...
$

It looks like build.jam still needs some work for VMS to eliminate
") in the link command.
