test_buckets.c gcc compile error on non-win32 (invalid // comment)

What steps will reproduce the problem?
1. Compile serf-1.3.8 (scons)
2. Run test suite (scons check) using gcc on Linux (or non-win32 platform)

What is the expected output? What do you see instead?
The test suite code should compile without errors (to allow the test suite to 
execute).

What version of the product are you using? On what operating system?
serf 1.3.8, CentOS Linux 6.5 x86_64, gcc 4.4.7

Please provide any additional information below.

1. CFLAGS '-std=c89' is set by SConstruct for non-win32 platforms
   if sys.platform != 'win32':
     ### gcc only. figure out appropriate test / better way to check these
     ### flags, and check for gcc.
     env.Append(CFLAGS='-std=c89')

2. test/test_buckets.c use a C++ style comment "//" not valid until C99 to 
comment out a line of code
   1237 //    buf_size = orig_len + (orig_len / 1000) + 12;

   The 1.3.x branch received this from trunk r2419.

3. scons check (command output)
...
