[boost] erfc id not found

I have been trying to compile code that uses the erfc function. I can get it to build successfully using DevC++4.9.9.2, but cannot using Win-Visual C++2005 Express (C90 standard) which I have been using to construct a form for input-output. I have downloaded the boost libraries and have changed the configuration properties to include the boost directory and changed to Not Using Precompiled Headers. I continue to receive the following: 'erfc': identifier not found. I have tried adding the libraies for DevC++4.9.9.2 but receive the same error. I am new to C++ and this a small simple program but am spending a significant amount of time getting the erfc issue resolved. Any help would be very appreciated. Thank you. Gary
