From: Junio C Hamano Date: Sat, 23 May 2009 01:06:06 +0000 (-0700) Subject: Teach Solaris that _XOPEN_SOURCE=600 really menas XPG6 X-Git-Tag: v1.6.4-rc0~95^2~1 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=30d8080ca76432a60142f6af04e477bfa24b7f4c;p=git.git Teach Solaris that _XOPEN_SOURCE=600 really menas XPG6 In git-compat-util.h, we do #define _XOPEN_SOURCE 600 #define _XOPEN_SOURCE_EXTENDED 1 unless we are on BSD or SCO. On OpenSolaris (200811), /usr/include/sys/feature_tests.h has this nice table: Feature Test Macro Specification ------------------------------------------------ ------------- _XOPEN_SOURCE XPG3 _XOPEN_SOURCE && _XOPEN_VERSION = 4 XPG4 _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1 XPG4v2 _XOPEN_SOURCE = 500 XPG5 _XOPEN_SOURCE = 600 (or POSIX_C_SOURCE=200112L) XPG6 Later in the same header, compilation with -c99 is made to fail if _XPG6 is not set, like this: #if defined(_STDC_C99) && (defined(__XOPEN_OR_POSIX) && !defined(_XPG6)) #error "Compiler or options invalid for pre-UNIX 03 X/Open applications \ and pre-2001 POSIX applications" #elif ... The problem is that they check things in an order that is inconvenient for us. When they see _XOPEN_SOURCE_EXTENDED, they declare that we are XPG4v2, regardless of the value of _XOPEN_SOURCE. To work around this problem, do not define _XOPEN_SOURCE_EXTENDED on Sun's.
