[svn-r8597] Purpose:

bug fix

Description:
Somehow in the function error_msg, a #ifdef WIN32 combine the stdout and stderr into a stdout for windows platforms. This will cause the confused output of dumper test on windows.
Erase this macro.

Solution:
See above.

Platforms tested:
windows XP with MSVS 6.0 by xuan.
No need to test on other platforms.

Misc. update:

tools/lib/h5tools_utils.c
