FMT_USE_NONTYPE_TEMPLATE_ARGS detection is wrong on trunk

[timsong-cpp]

With trunk GCC and -std=c++2c :

#include <fmt/compile.h>
using namespace fmt::literals;

int main() {
    fmt::print(""_cf);
}

does not compile with trunk fmt but does with 10.2.1:

https://gcc.godbolt.org/z/4WsvGP6bs

fmt/include/fmt/base.h

Lines 143 to 144 in aa52eb7

	#elif FMT_GCC_VERSION >= 903 && FMT_CPLUSPLUS >= 201709L
	# define FMT_USE_NONTYPE_TEMPLATE_ARGS 0

looks suspicious.

Good catch, thanks! Looks like I accidentally inverted this check when cleaning it up.

Fixed in #3937 (thanks @Arghnews).
