problem with C99 functions prototipes on Intel C 2017

Hi, 

I keep my Intel C compiler 2013 until recently. A few days ago I bought the 2017 version. The Intel C 2017 is integrated with VS 2015, Community Edition. 

I frequently use functions such as sincos() and sincosf().  With Intel C 2013, it is OK. But when I use the new compiler it complains for lack of prototipe, at compilation time, but after that the linker correctly find and link the symbol. The include of Intel Math library is present:

#include <mathimf.h>

And the language is specified as :  /Qstd=c99.   Were sincos() and sincosf() removed form mathimf.h ?

Thanks ,

Armando

A clarification:  sincos() and sincosf() are not part of C99 math library.  They have being part of <mathimf.h> for as long as I can remember.

More clarifications:

sincos()  and the rest of the family are resolved at link time.   The compiler emits warning for lack of function prototype but they are linked ok. And they are present at <mathimf.h>  but are not available for Windows compilation ( ? ).

On the other hand , the 2017 compiler is complaining about "long double"  . Even adding /Qlong-double it is emitting errors for not knowing the C99 standard long double type.

It is a very confusing situation for my understanding, a step back from composer XE 2013.
