BIG_ENDIAN bug in jpwl.c

[szukw000]

I compiled openjpeg2-git-2016-08-21 on a PPC64 machine:

Linux g5 3.16.0-4-powerpc64 #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) ppc64 GNU/Linux

The following error was reported:

---

/home/sources/LIB/OPENJPEG/openjpeg2-git-2016-08-21/src/bin/jpwl/convert.c:190:15: error:
unknown type name 'uint16_t'
static inline uint16_t swap16(uint16_t x)

/home/sources/LIB/OPENJPEG/openjpeg2-git-2016-08-21/src/bin/jpwl/convert.c:190:31: error:

static inline uint16_t swap16(uint16_t x)

make[2]: *** [src/bin/jpwl/CMakeFiles/opj_jpwl_compress.dir/convert.c.o] Error 1
make[1]: *** [src/bin/jpwl/CMakeFiles/opj_jpwl_compress.dir/all] Error 2
make: *** [all] Error 2

The report was triggered because of:

ifdef OPJ_BIG_ENDIAN

static inline uint16_t swap16(uint16_t x)
{
return(((x & 0x00ffU) << 8) | ((x & 0xff00U) >> 8));
}

endif

The patch is attached.

The patch looks good. Do you want to send a pull request?

Using byteswap.h and the bswap_16 macro would be an alternative solution.
