--- Comment #14 from TCH <tch at protonmail dot com> ---
The resulting binary however has a problem: it tries to use the non-GNU
assembler under '/usr/ccs/bin/as', instead of using the GNU assembler under
'/usr/local/as', despite being configured to use the GNU assembler and thus,
any compilation with it will fail:
/usr/ccs/bin/as: error: unknown option '3'
/usr/ccs/bin/as: error: unknown option '2'
usage: /usr/ccs/bin/as [-V] [-Q{y,n}] [-q] [-s]
[-S] [-K {pic,PIC}] [-o objfile] [-L] [-T]
[-P [[-Yc,path] [-Ipath] [-Dname] [-Dname=def] [-Uname]]...]
[-m [-Ym,path]] [-n] [-ul] [-xF]
[-m32] [-m64]
[-xarch={v7,v8,v8a,v8plus,v8plusa,v8plusb,v9,v9a,v9b,sparc,sparcvis,
sparcvis2,sparcfmaf,sparcima}]
[-xcode={pic13,pic32}] file.s...
This of course can be workarounded by backing up '/usr/ccs/bin/as' and
symlinking '/usr/local/bin/as' to there, but it should work without this.
Note: '/usr/local/bin' has higher priority in '$PATH' than '/usr/ccs/bin'.
Further note: to use it, first
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH"':/opt/csw/lib/'
needs to be done, or it will die:
ld.so.1: cc1: fatal: libmpc.so.3: open failed: No such file or directory
gcc: internal compiler error: Killed (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
This also means, that this exporting line must be moved from behind to before
the '../configure' line, if one tries to compile GCC6 with itself.
