Did you solve it?
No, project delayed until I'll have enough deep qualification in
system-level D coding
How/where are you referencing mmap64? Could some include be
missing or path issue?

Here the next problem of building `gcc-12.3.0` with
`uClibc-ng-1.0.44` (i386 target):
fixed by moving to `musl` usage -- not a surprise that `uClibc`
becomes obsoleted libc comparing their compilation time,
configuration complexity, and incompatibility with modern
toolchains
But the next li
Here the next problem of building `gcc-12.3.0` with

```
libtool: compile:
/home/ponyatov/player/tmp/gcc-12.3.0-1/./gcc/gdc

-B/home/ponyatov/player/host/i686-linux-uclibc/bin/
-B/home/ponyatov/player/host/i686-l
You'll need at least gcc-9/gdc-9 to build gcc-13.
Version problem was fixed by building `gcc-12.3.0` with `gdc`
enabled on local host, and using it for the whole build in place
of system-provided `gcc` toolchain.

I'm trying to build a tiny Linux system with cross-compiling GDB:
