[Bridge] [PATCH] rstp compiling under gcc 4.3.3 fixes

[Denys Fedoryschenko <denys@visp.net.lb>]

Sorry, properly formatted

rstp git tree:
After fetching current git code and compiling with gcc 4.3.3 got errors 
related to Werror (2 functions was ignoring return value), and ulimits.h was 
not declared, but INT_MAX used
Here is fix, so rstp compile fine with gcc 4.3.3.
