I need help with this error.
Using source file including <math.h>, the include hierarchy is
bands.c
Note: including file: ../opus-1.3-rc2/win32/config.h
Note: including file: .\version.h

D:\develop\Intel\compilers_and_libraries_2019.0.117\windows\compiler\include\math.h(695): error #1739: redeclaration cannot add dllexport/dllimport to "ldexpf" (declared at line 721 of "D:\Microsoft\Visual Studio 2013\VC\include\math.h")
_LIBIMF_EXTERN_C float _LIBIMF_PUBAPI ldexpf( float __x, int __exp );
^Here when the parsing returns back to Intel's math.h, the redeclared ldexpf in MSC native header is in some collision
My question is how to bypass the error.

I also remark that $(ICInstallDir)\include\icc needs to be included in incpath to prefere Intel's xmmintrin.h. The replacement is not automatic as Intel's header file is in icc\ subfolder not prefixed anywhere. Is this intentional?
