Currently you need to also use --with-newlib, which is confusing for users who aren't actually using newlib. The AM_PROG_LIBTOOL checks are currently skipped for --with-newlib and --with-avrlibc builds, with this change they are also skipped when using --without-headers. It would be nice if using --disable-hosted-libstdcxx automatically skipped those checks, but GLIBCXX_ENABLE_HOSTED comes too late to make the AM_PROG_LIBTOOL checks depend on $is_hosted. The checks for EOF, SEEK_CUR etc. cause the build to fail if there is no available. Unlike most headers, which get a HAVE_FOO_H macro, is in autoconf's default includes, so every check tries to include it unconditionally. This change skips those checks for freestanding builds. Similarly, the checks for types done by GCC_HEADER_STDINT try to include and fail for --without-headers builds. This change skips the use of GCC_HEADER_STDINT for freestanding. We can probably stop using GCC_HEADER_STDINT entirely, since only one file uses the gstdint.h header that is generated, and that could easily be changed to use instead. That can wait for stage 1. We also need to skip the GLIBCXX_CROSSCONFIG stage if --without-headers was used, since we don't have any of the functions it deals with. The end result of the changes above is that it should not be necessary for a --disable-hosted-libstdcxx --without-headers build to also use --with-newlib. Finally, compile libsupc++ with -ffreestanding when --without-headers is used, so that will use instead of expecting it to come from libc. libstdc++-v3/ChangeLog: PR libstdc++/103866 * acinclude.m4 (GLIBCXX_COMPUTE_STDIO_INTEGER_CONSTANTS): Do nothing for freestanding builds.
