According to the ISO C standard, lgamma(-integer) returns
inf and raises the divided-by-zero exception.  Compilers
constant fold one/zero to inf but do not raise the exception.
Introduce a volatile vzero to prevent the constant folding.

Move the declaration of zero into the main declaration block.

While here, fix a nearby disordering of 'lx,ix'
