snprintf is not a member of std

I am working on an Xcode project that includes boost thread library through cross-project reference. One step of setting up cross-project reference is to add value for Header Search Paths setting under Build tab (from project target's Get Info option). While doing so, I have checked the Recursive check-box.

When the project is built, the following error occurs:

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/usr/include/c++/4.0.0/i686-apple-darwin9/bits/c++locale.h:72: error: 'snprintf' is not a member of 'std'

Googling leads to a solution - Uncheck the Recursive check-box.

Xcode version I am working with is 3.1.4.
