You're right, missed that.
The header has:
/* Defined to a complex binary128 type if __HAVE_FLOAT128 is 1. */
# if __HAVE_FLOAT128
# if __LDBL_MANT_DIG__ == 113 && defined __cplusplus
typedef long double _Float128;
# define __CFLOAT128 _Complex long double
# elif !__GNUC_PREREQ (7, 0) || defined __cplusplus
/* The type _Float128 exist for powerpc only since GCC 7.0. */
typedef __float128 _Float128;
/* Add a typedef for older GCC and C++ compilers which don't natively support
_Complex _Float128. */
typedef _Complex float __cfloat128 __attribute__ ((__mode__ (__KC__)));
# define __CFLOAT128 __cfloat128
# else
# define __CFLOAT128 _Complex _Float128
# endif
# endif
and my current rules don't do anything about that.
The following patch fixes that.
I've run additionally
MACRO_LIST=`pwd`/../gcc/macro_list TARGET_MACHINE=x86_64-pc-linux-gnu ../fixincludes/fixinc.sh /tmp/include-fixed `echo /usr/src/libc | sed -e :a -e 's,[^/]*/\.\.\/,,' -e ta`
in the builddir/fixincludes directory where /usr/src/libc is latest glibc
trunk checkout and seems the remaining defined __cplusplus cases in the floatn.h
and floatn-common.h headers are ok or acceptable.
The remaining cases are:
#if __GNUC_PREREQ (7, 0) && !defined __cplusplus
# define __HAVE_FLOATN_NOT_TYPEDEF 1
#else
# define __HAVE_FLOATN_NOT_TYPEDEF 0
#endif
which is IMHO ok because this is only used in tgmath.h or tgmath-like math.h
stuff which is C only, as C++ doesn't have _Generic.
Another case are the following 3 snippets:
# if !__GNUC_PREREQ (7, 0) || defined __cplusplus
# error "_Float128X supported but no constant suffix"
# else
# define __f128x(x) x##f128x
# endif
...
# if !__GNUC_PREREQ (7, 0) || defined __cplusplus
# error "_Float128X supported but no complex type"
# else
# define __CFLOAT128X _Complex _Float128x
# endif
...
# if !__GNUC_PREREQ (7, 0) || defined __cplusplus
# error "_Float128x supported but no type"
# endif
but as no target has _Float128x right now and don't see it
coming soon, it isn't a big deal (on the glibc side it is of
course ok to adjust those).
OT, besides floatn.h and floatn-common.h headers, the only
one remaining in /tmp/include-fixed is sysdeps/arm/unwind.h, perhaps
-#if defined(linux) || defined(__NetBSD__)
+#if defined(__linux__) || defined(__NetBSD__)
should be done in that header (and libgcc/config/arm/unwind-arm.h
too).
Ok for trunk?
BTW, we have some multi-arch related issue with fixincludes too, apparently
fixincludes never worked properly on multi-arch (aka Debian/Ubuntu) :(.

This incremental patch deals handles the above 3 cases, so we
fixinclude what glibc itself changed too.
Bootstrapped/regtested on x86_64-linux and i686-linux (together with the
previously posted fixincludes/ change too), ok for trunk?

Hi,
The combination of these two patches allows me to build gcc
successfully. (PPC64LE with RHEL9).
A nit that Part1 needed massaging
of the path/to/files (i.e. gcc/inclhack.def versus
