re PR c/15360 (c99: extern w/initializer; extern w/internal linkage)
PR c/15360
* c-decl.c (start_decl): Do not set DECL_EXTERNAL for initialized
declarations until after calling pushdecl.
(grokdeclarator): Set DECL_EXTERNAL for variables based on use of
"extern" and not on whether the declaration is initialized.
testsuite:
* gcc.dg/pr15360-1.c: New test.
