Use of CFLAGS in a library

[frmaioli]

Hi All,

I need to make a static library that will work in different environments (kernel and application). I have already done everything and I could generate the "mylib.a".

The doubt is about the flags options used in gcc to compile the library.
My first test I have not inserted any flag and I inserted the "mylib.a" in the kernel compilation. To test I made a driver that access the library functions. For my surprise it worked!

Why didn't I need to use the same CFLAGS used in the kernel (with all optimizations) in my lib? I really thougth that the kernel compilation would warn.

Thanks.
