Hi,

for this error message about the types involved in array subscripting I 
think we can exploit the available location argument and point to the 
open square bracket instead of simply using input_location. Tested 
x86_64-linux.

Thanks, Paolo Carlini.

	* decl2.c (grok_array_decl): Use the location of the open square
	bracket in error message about invalid types.

/testsuite
2019-08-13  Paolo Carlini  <paolo.carlini@oracle.com>

	* g++.dg/conversion/simd4.C: Test locations.
