From 920a69a8d8e4203c5edddd829d932130eac188ea Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Wed, 26 May 2010 10:36:46 +0300 Subject: Rename MIN() and MAX() to my_min() and my_max(). This should avoid some minor portability issues. --- src/common/sysdefs.h | 12 +++++------- src/liblzma/common/block_buffer_encoder.c | 2 +- src/liblzma/common/common.c | 2 +- src/liblzma/common/stream_buffer_encoder.c | 2 +- src/liblzma/delta/delta_encoder.c | 2 +- src/liblzma/lz/lz_decoder.c | 7 ++++--- src/liblzma/lz/lz_decoder.h | 2 +- src/liblzma/lz/lz_encoder.c | 2 +- src/liblzma/lz/lz_encoder.h | 2 +- src/liblzma/lz/lz_encoder_mf.c | 4 ++-- src/liblzma/lzma/lzma2_encoder.c | 2 +- src/liblzma/lzma/lzma_encoder_optimum_fast.c | 2 +- src/liblzma/lzma/lzma_encoder_optimum_normal.c | 14 +++++++------- src/xz/args.c | 3 ++- 14 files changed, 29 insertions(+), 29 deletions(-) (limited to 'src') diff --git a/src/common/sysdefs.h b/src/common/sysdefs.h index 61ac0b40..1e138b1c 100644 --- a/src/common/sysdefs.h +++ b/src/common/sysdefs.h @@ -156,13 +156,11 @@ typedef unsigned char _Bool; #undef memzero #define memzero(s, n) memset(s, 0, n) -#ifndef MIN -# define MIN(x, y) ((x) < (y) ?
