PR c/39605
* c-decl.c (grokdeclarator): Pedwarn for file-scope array
declarator whose size is not an integer constant expression but
folds to an integer constant, then treat it as a constant
subsequently.
testsuite:
* gcc.dg/vla-17.c, gcc.dg/vla-18.c: New tests.
* gcc.dg/pr25682.c: Update expected diagnostics.
