[Bug c++/107128] armhf: floatn-common.h:214:9: error: multiple types in one declaration
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107128 --- Comment #10 from CVS Commits --- The trunk branch has been updated by Jason Merrill : https://gcc.gnu.org/g:538a0d0f29b12cff05681b6de2e0a3d7b33f3ef0 commit r13-6643-g538a0d0f29b12cff05681b6de2e0a3d7b33f3ef0 Author: Jason Merrill Date: Mon Mar 13 14:06:11 2023 -0400 c++: handle _FloatNN redeclaration like bool [PR107128] It's been inconvenient to compile testcases preprocessed with GCC 12 or earlier because they break on typedef __float128 _Float128; We already had code for handling this with bool and wchar_t, it just needs to be extended to _FloatNN as well. PR c++/107128 gcc/cp/ChangeLog: * parser.cc (cp_parser_set_decl_spec_type): Use redefined_builtin_type for extended_float_type_p. gcc/testsuite/ChangeLog: * g++.dg/warn/pragma-system_header6.h: New test. * g++.dg/warn/pragma-system_header6.C: New test.

I wonder why the sysroot path didn't appear in those messages... You need to use fixincludes with gcc 13+ unless you have very old or very fresh glibc.

I wonder why the sysroot path didn't appear in those messages... Can you file a new bug. Fixincludes should be happening for the sysroot but maybe a setting is wrong. Please include how you configured gcc.
