GSL test release 1.12.90

[Brian Gladman <brg@gladman.plus.com>]

I have compiled GSL 1.12.90 and the tests on Vista x64 Ultimate using
Visual Studio 2008 Professional (a few minor changes are needed to do
this).

I had two compile errors:

1. I found declarations after executable statements in test_funcs.c
(spring_f)

2. In gsl_const_cgs.h, the MSVC preprocessor does not recognise the
#warning directive.

After removing these compilation errors, all tests except one pass in
both 32 and 64 bit versions of the library.

The test that fails is testrandist, which gives this output in 64-bit mode:

GSL_IEEE_MODE="double-precision,round-to-nearest,mask-all"
FAIL: test gsl_ran_exponential [0,1]
      (0 observed vs 0.393469 expected) [7]

and this in 32-bit mode:

GSL_IEEE_MODE="double-precision,round-to-nearest,mask-all"
FAIL: test gsl_ran_exponential [0,1]
      (0 observed vs 0.393469 expected) [7]
FAIL: test gsl_ran_discrete1 [-0.5,0.5]
      (0.33122 observed vs 0.59 expected) [9]
FAIL: test gsl_ran_discrete1 [0.5,1.5]
      (0.33343 observed vs 0.4 expected) [10]
FAIL: test gsl_ran_discrete1 [1.5,3.5]
      (0.33164 observed vs 0.01 expected) [11]

I have not yet had time to look into this failure any further.

My thanks to all developers for their first class work on GSL.
