Some platforms support 64 bit 'long long', but you can not printf or scanf

Browse Source 
2000-09-28  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in, tests/type-test.c: Some platforms support 64 bit
	'long long', but you can not printf or scanf them. In that case,
	don't define G_G{UINT|INT}64_FORMAT. Changed the type-test program
	to reflect that.

statically as it might call a function. So do it at first call.
