Update from version 2.010709 to 2.010800.  Changes:

2.010800:
	Test suite was sub()ifying argument to sumnuminit().
	Test suite would not correctly sub()ify intnum() if limits had "()".
	Test suite calculated Pi Euler too early; Now only these fail
    t/55_intnum.t               51    1   1.96%  12
    t/55_ploth.t                34    1   2.94%  4

  # eval-noans: $oo=[  PARI(1) ];
  # eval-noans: setprecision(96)
  # eval-noans: $tab=intfuncinit($t,[-$oo,4.5],[$oo,4.5], sub{gamma(2+ I*$t)**3},1);
  # eval: intmellininvshort(2,4,$tab)-$A
  not ok 12 # in='intmellininvshort(2,4,$tab)-$A'

  # re_out='\-3\.072350108,?\s*E\-97,?\s*\+,?\s*9\.90717831,?\s*E\-100\*I'

	Why this succeeds?
  # eval: intnum($x,-1,1, \ 
sub{intnum($y,-sqrt(1-$x**2),sqrt(1-$x**2),$x**2+$y**2,$tab)},$tab)- Pi/2
	Actually, $x**2+$y**2 is converted to a string as in '0.09+y^2',
	 which is interpreted by GP/PARI.
	Add warnings to the test suite for detection of #@_
	 in Perl-in-PARI-in-Perl calls.
	Attempt to support v5.10 (based on code contributed by ???)
