runtime libs linked in to exe, IDA question.

[Wannabe]

Using PEID I identified the EXE as a Visual C++ application, and loaded FLIRT signatures for Visual C++ runtime libraries. IDA then correctly identified some low-level funtions like GlobalAlloc, ReadFile and such. But no printfs, strcpy and alike. Am I missing something here? Didn't find FLIRTS for the standard libraries. Are you supposed to have the compiler in question and make your own FLIRTS? The help file included, which is the only documentation I have, seemed a bit rudimentary for me.
Grateful for any help, just recently got hold of this IDA and haven't had much time learning all the features yet. Guess I was so eager to reverse this puppy
