stdout and stderr outputs could be messed up

[GoogleCodeExporter]

What steps will reproduce the problem?
1. compile the standard cmockery example 'assert_macro_test.exe' on Windows
2. execute "assert_macro_test.exe 1>output 2>&1"

What is the expected output? What do you see instead?

The file "output" should contain:

get_status_code_string_test: Starting test
"Connection dropped" != "Connection timed out"
ERROR: ..\src\example\assert_macro_test.c:29 Failure!
get_status_code_string_test: Test failed.
string_to_status_code_test: Starting test
0x2 != 0x1
ERROR: ..\src\example\assert_macro_test.c:35 Failure!
string_to_status_code_test: Test failed.
2 out of 2 tests failed!
    get_status_code_string_test
    string_to_status_code_test

but it contains:

get_status_code_string_test: Starting test
get_status_code_string_test: Test failed.
string_to_status_code_test: Starting test
string_to_status_code_test: Test failed.
"Connection dropped" != "Connection timed out"
ERROR: ..\src\example\assert_macro_test.c:29 Failure!
0x2 != 0x1
ERROR: ..\src\example\assert_macro_test.c:35 Failure!
2 out of 2 tests failed!
    get_status_code_string_test
    string_to_status_code_test

What version of the product are you using? On what operating system?

1. cmockery 0.1.2
2. Windows XP SP3
3. Visual Studio 2008

Please provide any additional information below.

fflush() function should be called after each line printed to the stdout or 
stderr.
