I just started building GDC-5, so I figured I'd use GCC-5.1.0 (for easy transition from 4.9).

It turns out that GDC-5 will not build; the file ...

gcc/d/d-lang.cc

... fails on this line ...

3c59416a gcc/d/d-lang.cc 2016-10-29 00:51:04 +0200 1517)
       debug_hooks->register_main_translation_unit (global_context);

... because register_main_translation_unit is not a member of gcc_debug_hooks.
I've found out that this member was first seen in GCC-5.2.0.

Note: I'm now attempting to build GDC-5.2.0.

I'm not so sure such a change would happen in a minor release.  But in any case I'd say it can't be assumed that a version branch will work with anything except the latest release in that series.

My attempt to build 5.2.0 also failed, but with a more fatal error:

/Users/build/toolchain/Source/gcc-5.2.0+gdc/libgcc/libgcc2.c: In function '__muldc3':
/Users/build/toolchain/Source/gcc-5.2.0+gdc/libgcc/libgcc2.c:1992:1: internal compiler error: in create_edge, at cgraph.c:869

OK, I'll attempt to build 5.3.0 and 5.4.0 but I will not expect 5.3.0 to work. ;)

That's not GDC related though ;-)

It's a bug in GCC, which is triggered only when building GDC, not when building GCC with c,c++and lto (same configuration otherwise).

GCC-4.9.3 builds OK.
GCC-4.9.3+GDC builds OK.
GCC-4.9.4 builds OK.
GCC-4.9.4+GCC fails.

GCC-5.1.0+GDC fails (due to register_main_translation_unit)
GCC-5.2.0+GDC fails (internal compiler error)
GCC-5.3.0+GDC fails (internal compiler error)
GCC-5.4.0+GDC fails (internal compiler error)

This means my latest GDC is 4.9.3.

When the current build is finished, I'll try and revert back to an old gdc-5 (before the register_main_translation_unit change) and see if that will build.

Sorry, I was wrong; I confused myself by building GCC_5.1.0 as stand-alone (argh).

Building GCC-5.2.0 to GCC-5.4.0 (with or without GDC) fails with the error mentioned above.

I'll try and contact the GCC team; maybe they have a suggestion for a fix or workaround.
