--- Comment #3 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Issue still exists for ia64 and cygwin/mingw targets on 4.9.

The following files are including auto-host.h header:
- config/i386/cygming-crtbegin.c
- config/i386/cygming-crtend.c
- config/i386/cygming-crtend.c
- config/i386/cygwin.S
- config/ia64/crtbegin.S
- config/ia64/crtend.S
- crtstuff.c

In config/ia64/t-ia64-elf there is a tweak for finding this include-file.

The macros required in crtstuff.c are:
- HAVE_GAS_HIDDEN
- HAVE_LD_EH_FRAME_HDR

The cygwin/mingw part uses:
- DEFAULT_USE_CXA_ATEXIT
- HAVE_LD_RO_RW_SECTION_MIXING
- HAVE_GAS_WEAK
- HAVE_GAS_CFI_SECTIONS_DIRECTIVE

The macros required in ia64 are:
- HAVE_INITFINI_ARRAY_SUPPORT
- USE_GAS_SYMVER

So a lot of infrastructure of gcc needs to be ported to libgcc for detecting
and probs for ld vs. gold, and as.
