Hello,
The attached patch is a proposal for a basic solution
to an issue which might be an improper thing done by a
system header on VxWorks, but which is a big pain to fix
at this level and very simple to address super locally.
A number of tests based on gcc.dg/vect/tree-vect.h
#define and then use a macro named OFFSET, which conflicts
with a macro of the same name exposed by a system
header on VxWorks.
The patch proposed here simply #undef's OFFSET from
tree-vect.h to prevent the possible conflict.
Is this OK to commit ?
Thanks a lot in advance,
With Kind Regards,
Olivier
