The boot compiler is GCC 12.1.0.

Configuration fails because the C compiler can’t produce an executable. I don’t have the log, but the errors were like

configure:3943: gcc -c -g  conftest.c >&5
<built-in>: error: unknown value '13.0.0' of '-mmacosx-version-min'

I tried setting CFLAGS and CXXFLAGS as here:

export CFLAGS=-mmacosx-version-min=12.0.0
export CXXFLAGS=-mmacosx-version-min=12.0.0

$GCC_SRC/configure                                                      \
  --prefix=$PREFIX                                                      \
  --without-libiconv-prefix                                             \
  --disable-libmudflap                                                  \
  --disable-libstdcxx-pch                                               \
  --disable-libsanitizer                                                \
  --disable-libcc1                                                      \

  --disable-nls                                                         \
  --enable-languages=c,c++,ada                                          \
  --host=$BUILD                                                         \
  --target=$BUILD                                                       \
  --build=$BUILD                                                        \
  --without-isl                                                         \
  --with-build-sysroot="$(xcrun --show-sdk-path)"                       \
  --with-sysroot=                                                       \
  --with-specs="%{!sysroot=*:--sysroot=%:if-exists-else($XCODE $CLU)}"  \
  --with-build-config=no                                                \
  --enable-bootstrap                                                    \
  CFLAGS=-mmacosx-version-min=12.0.0                                    \
  CXXFLAGS=-mmacosx-version-min=12.0.0 

(having checked that this flag was needed to avoid the error in a standard-alone compilation) but the configure now failed in fixincludes/. It seems that sometimes the CFLAGS setting is used and sometimes it isn’t??? See lines 3674, 3744, 3800, 3857, 3905 below and then 3943

I’m 99% sure that this issue is down to the problem fixed in https://github.com/gcc-mirror/gcc/commit/6725f186cb70d48338f69456864bf469a12ee5be <https://github.com/gcc-mirror/gcc/commit/6725f186cb70d48338f69456864bf469a12ee5be> - which is included in GCC 12.2 - so I’ll go build 12.2.0 & try again
