gsl-1.10 "make check" for "linalg" and "randist" -- test.c does not compile

[mrengert@..........]

Hi ?

First ? thanks very much for great free software libraries.

I found two minor issues in the GSL library package ?gsl-1.10?

I built GSL on a sparc / Solaris 10:

   $ uname -a
   SunOS cod 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-V210

And configured the build with ?configure ?prefix=$HOME CC=/opt/SUNWspro/bin/cc?

----------

Two files fail to compile when making "check", because assignment statements are
intermixed with declaration statements (is legal in c++, maybe?)

The files are:  linalg/test.c  and  randist/test.c.

After moving the offending statements down after the last declaration, all was well.

Below I have included a diff for the offending statements.
