Subject: [PATCH] src/regex.c: support old compilers for the endian
|
|
check
|
|
|
|
libselinux 2.6 has added some code in regex.c that uses __BYTE_ORDER__
|
|
to determine the system endianness. Unfortunately, this definition
|
|
provided directly by the compiler doesn't exist in older gcc versions
|
|
such as gcc 4.4.
|
|
|
|
In order to address this, this commit extends the logic to use
|
|
<endian.h> definitions if __BYTE_ORDER__ is not provided by the
|
|
compiler. This allows libselinux to build properly with gcc 4.4.
