Now that libm/Makefile enabled lint (in revision 1.83)
VAX build fails in libm.

Lint complains about unexpected open bracket in complex designated
initializer in mathimpl.h, wrapped below for readability:

const union { long l[2]; double d; } cat3(__,name,x) = {
   .l[0] = cat3t(0x,x1,x2),
   .l[1] = cat3t(0x,x3,x4)
};

.memeber[index] syntax confuses lint.

>How-To-Repeat:
Try building current for VAX.

>Fix:
One possible workaround would be to simplify the initializer to

  { .l = { [0] = ..., [1] = ... } };

but unfortunately that triggers another bug (lint dumps core)
that I will file separately.
