Everything [except the `make install`] appears to work well. Only the `make install` of gcc 4.3.6 fails. It dies with this error: > > cc1: error: unrecognized command line option "-Wno-overlength-strings" > > gmp,mpfr, and mpc all compiled without error, passed `make check`, and were installed via `make install.` There were no issues. GCC 4.3.6 compiles without error (make) and passes almost 96,000 tests before `make check` dies (after >2hrs using -j4).

I Googled until I reached the end of the Internet... and, well, after that I decided to write this e-mail. What gives? Is there an environment variable that can be set to force gcc to not attempt to use this option (in the configure logs, it discovers that "-Wno-overlength-strings" is not an available option. WTF? We've run into this several times with 4.3. Never did find a solution and ended up going away with 4.4. https://bugs.gentoo.org/241604 Comment 13 (which i sadly just noticed now): Since this is the "make install" stage, there shouldn't be any recompilation necessary, but in my log file, it shows that "Must remake target `cc1-checksum.o'", which caused the compile error mentioned in the opening. The interesting bit is that inside the work/build/gcc dir there is a "cc1-checksum.c" file, but no .o nor executable was created for it (but cc1plus-checksum.o does exist). -- fonts, gcc-porting, it makes no sense how it makes no sense toolchain, wxwidgets but i'll take it free anytime @ gentoo.org EFFD 380E 047A 4B51 D2BD C64F 8AA8 8346 F9A4 0662
