The MSVC 9 compiler does not define __STDC__. And we cannot define __STDC__,
because then many declarations will be hidden in the system header files.
So the workaround is either to test for _MSC_VER explicitly (this is what the
GNU standards recommend [1]), or to assume an ANSI C compiler outright.

iconv, unsetenv: Add support for MSVC compiler.
* m4/iconv.m4 (AM_ICONV): Use ISO C declaration syntax on MSVC.
* m4/setenv.m4 (gl_FUNC_UNSETENV): Drop support for K&R C compilers.
