Compatibility with GCC 7 + glibc 2.27

Hello,

I'm using the Intel Compiler 2018 Update 2 on Linux x86_64 (Arch Linux). Arch Linux's default compiler and glibc versions are GCC 7.3.1 and glibc 2.27 at the moment. In

I reported an incompatibility of ICC 17 when used with GCC 7 + glibc 2.26. This incompatibility is now fixed, but similar problems have now arisen with glibc 2.27. glibc 2.27 adds a few function declarations for the _Float32, _Float32x, _Float64, _Float64x, ... types in case the corresponding __HAVE_FLOATXYZ macros are defined, for example:
 

#if __HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT) 
extern _Float32 strtof32 (const char *__restrict __nptr, 
                         char **__restrict __endptr)
    __THROW __nonnull ((1));
#endif

This fails to compile with Intel Compiler 2018 Update 2, when using GCC 7. GCC 7 is needed because one of its headers will define the __HAVE_FLOATXYZ macros (see https://gcc.gnu.org/gcc-7/changes.html, search for Float32).

Another unrelated incompatibility with glibc 2.27 is this part in the Intel Compiler math.h:

#if (!defined(__linux__) || !defined(__USE_MISC)) && !defined(__NetBSD__) || defined (__PURE_INTEL_C99_HEADERS__)
typedef enum ___LIB_VERSIONIMF_TYPE {
     _IEEE_ = -1    /\* IEEE-like behavior    *\/
    ,_SVID_         /\* SysV, Rel. 4 behavior *\/
    ,_XOPEN_        /\* Unix98                *\/
    ,_POSIX_        /\* Posix                 *\/
    ,_ISOC_         /\* ISO C9X               *\/
} _LIB_VERSIONIMF_TYPE;
#else
# define _LIB_VERSIONIMF_TYPE _LIB_VERSION_TYPE
#endif

_LIBIMF_EXTERN_C _LIB_VERSIONIMF_TYPE _LIBIMF_PUBVAR _LIB_VERSIONIMF;

This part of math.h causes a compilation failure because glibc 2.27 removed the macro '_LIB_VERSION_TYPE' (https://sourceware.org/git/?p=glibc.git;a=commit;h=813378e9fe17e029caf62...).

I realize that the current version of the compiler does not officially support glibc 2.27, but it would be nice to have this fixed in a future release, which is why I'm reporting these incompatibilities here.
