Subject: Only build the 'dl' extension when sys.maxint equals 2**31-1.
X-Git-Tag: v2.3c1~4113
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=770acd3f7fff52eef0d0ad02beaa4c569d70811f;p=thirdparty%2FPython%2Fcpython.git

Only build the 'dl' extension when sys.maxint equals 2**31-1.
This module raises "SystemError: module dl requires sizeof(int) ==
sizeof(long) == sizeof(char*)" when compiled on 64-bit platforms.
