* c-common.c (valid_array_size_p): New function.
* c-common.h (valid_array_size_p): Declare.
* c-decl.c (grokdeclarator): Call valid_array_size_p. Remove code
checking the size of an array.
* decl.c (grokdeclarator): Call valid_array_size_p. Remove code
checking the size of an array.
* c-c++-common/pr68107.c: New test.
* g++.dg/init/new38.C (large_array_char): Adjust dg-error.
(large_array_char_template): Likewise.
* g++.dg/init/new44.C: Adjust dg-error.
