Building GCC for vxWorks

["Maldonado-Salgado, Jose (Space Technology)" <jose dot maldonado-salgado at ngc dot com>]

When Building gcc for vxWorks, do I need to specify the
--enable-threads=vxworks ??
I did included that in my configure command, but when compiling, it
tries to compile the file
vxLib.c  which seems to use definitions of MACROS and types that are
defined in the vxWorks
include files that comes in the Wind Rivers distribution of vxWorks.
Do I need to include in
the make, a way of seeing the Wind Rivers include files ?   Where would
I add the "-I with the path to the wind rivers files" if that is what it
takes to be able to compile ?

Thanks,
Jose
