* c-decl.c (grokdeclarator): Don't give a warning about defaulting
to int for plain complex which defaults to complex double. Do
warn about defaulting to complex double if pedantic. Warn about
complex integer types if pedantic. Warn about complex types if
pedantic and not in C99 mode.
* c-typeck.c (build_unary_op): If pedantic, warn about use of ~
for complex conjugation.
testsuite:
* gcc.dg/c90-complex-1.c, gcc.dg/c99-complex-1.c: New tests.
