From 9328ad6bf8f2652faa7b7568504c1abe7e4b513a Mon Sep 17 00:00:00 2001 From: kan Date: Sun, 4 May 2003 22:13:04 +0000 Subject: Style fixes. Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they were marked for deprecation ever since SUSv1 at least. Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is supported. Restore a lost comment in MI _limits.h file and remove it from sys/limits.h where it does not belong. --- sys/arm/include/_limits.h | 19 +++++++++++-------- 1 file changed, 11 insertions(+), 8 deletions(-) (limited to 'sys/arm/include') diff --git a/sys/arm/include/_limits.h b/sys/arm/include/_limits.h index ce1cd20..321a769 100644 --- a/sys/arm/include/_limits.h +++ b/sys/arm/include/_limits.h @@ -39,6 +39,17 @@ #define __CHAR_BIT 8 /* number of bits in a char */ +/* + * According to ANSI (section 2.2.4.2), the values below must be usable by + * #if preprocessing directives.
