Subject: std_complex.h (norm): Forward declare.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=99fa3f5eddb9b963d43c55444705af6c2e3daf4a;p=gcc.git

std_complex.h (norm): Forward declare.

	* include/bits/std_complex.h (norm): Forward declare.
	(complex<>): Comment out friend declaration of conj<>.
	(conj<>): Comment out specialization.
	(exp, log, log10): Define primary templates.

	* src/complex.cc (exp<>, log<>, log10<>): Comment out
	specializations.
