c-lex.c (lex_number): If pedantic and not C99... 

* c-lex.c (lex_number): If pedantic and not C99, pedwarn exactly
	once for hexadecimal floats, whether or not they contain a decimal
	point.  Don't let the setting of pedantic otherwise affect the
	parsing of hexadecimal floats.

testsuite:
	* gcc.dg/c90-hexfloat-1.c: Add more tests.
