Re: [Tinycc-devel] sinf/sin problems

[Aharon Robbins]

The problem is apparently that sinf isn't declared in Microsoft's <math.h>
header file; try searching MSDN to see where it is declared.

What's happening is that C treats undeclared functions as being
implicitly declared to return int (4 bytes), which explains why
you're getting bad values.  If you explicitly declare the function:

        extern double sinf(double);

things should start working.

In short, tcc is behaving properly; the headers / library aren't
matching your expectations.

HTH,
