From 5985c772100b698aa6cf77997b06e4cfd047e7e7 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 16 Sep 2000 01:39:48 +0000 Subject: Update. * math/complex.h: Don't define _Complex macro for gcc 3. Add __extension__ to _Complex_I definition since gcc warns if -pedantic. * math/bits/cmathcalls.h (conj): Add __extension__ since we use ~. --- math/bits/cmathcalls.h | 2 +- math/complex.h | 5 +++-- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'math') diff --git a/math/bits/cmathcalls.h b/math/bits/cmathcalls.h index 57a2582d70..3a46822cb5 100644 --- a/math/bits/cmathcalls.h +++ b/math/bits/cmathcalls.h @@ -151,7 +151,7 @@ __MATH_PRECNAME(creal) (_Mdouble_complex_ __z) __THROW extern __inline _Mdouble_complex_ __MATH_PRECNAME(conj) (_Mdouble_complex_ __z) __THROW { - return ~__z; + return __extension__ ~__z; } #endif diff --git a/math/complex.h b/math/complex.h index bd471263e6..ac08875adc 100644 --- a/math/complex.h +++ b/math/complex.h @@ -33,15 +33,16 @@ __BEGIN_DECLS /* We might need to add support for more compilers here.
