I was trying to figure this out with Iain on IRC the other day, but we never
managed to solve it, so I'm putting it here so it doesn't get lost:
Lately (as of r15-1899-g2b3027bea3f218) when I've been trying to build GCC with
Ada, I've been getting errors like the following:
mkdir -p ada/gen_il
cd ada/gen_il; gnatmake -q -g -gnata -gnat2012 -gnatw.g -gnatyg -gnatU
-I/Users/ericgallager/gcc_newgit/gcc/ada gen_il-main
# Ignore errors to work around finalization issues in older compilers
cd ada/gen_il; ./gen_il-main

Apparently __builtin_nested_func_ptr_created has been renamed to
__gcc_nested_func_ptr_created in recent revisions, so I don't get why the build
process is still looking for the old name? Here's what shows up when I search
the repo for the common part shared between those strings:

So, none of the Ada source files used to build gen_il-main contain references
to it... I'm wondering if it might be due to the version of gnatmake I'm using
to bootstrap? Here's its version info:
$ /usr/local/bin/gnatmake --version
GNATMAKE 14.0.0 20231204 (experimental) [master 2fde54ad7be]

(and yes, I've already tried seeing if this might be due to a configure flag I
was using, but it happens no matter the combination of configure flags that I
try...)
Perhaps related to bug 106487? Except I'm on x86_64...
