The reason for the failure is that somehow the CFLAGS for the bootstrap Sun compiler are getting passed to the just-built xgcc during building of libgcc. I suspect an environmental problem. Do you have CFLAGS_FOR_TARGET set by any chance? >From gcc/Makefile.in: LIBGCC2_CFLAGS = -O2 $(LIBGCC2_INCLUDES) $(GCC_CFLAGS) $(TARGET_LIBGCC2_CFLAGS) \ $(LIBGCC2_DEBUG_CFLAGS) $(GTHREAD_FLAGS) \ -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED \ $(INHIBIT_LIBC_CFLAGS) ...where GCC_CFLAGS is: GCC_CFLAGS=$(CFLAGS_FOR_TARGET) $(INTERNAL_CFLAGS) $(X_CFLAGS) $(T_CFLAGS) $(LOOSE_WARN) -Wold-style-definition $($@-warn) -isystem ./include $(TCFLAGS) ...and: INTERNAL_CFLAGS = -DIN_GCC @CROSS@ The actual expansion of all this is: /opt/build/gcc-4.2.2-build/./gcc/xgcc -B/opt/build/gcc-4.2.2-build/./gcc/ -B/export/home/dclarke/local/sparc-sun-solaris2.8/bin/ -B/export/home/dclarke/local/sparc-sun-solaris2.8/lib/ -isystem /export/home/dclarke/local/sparc-sun-solaris2.8/include -isystem /export/home/dclarke/local/sparc-sun-solaris2.8/sys-include -O2 -O2 -xstrconst -xildoff -xarch=v7 -xcode=pic32 -xlibmieee -xlibmil -Xa -xregs=no%appl -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I/opt/build/gcc-4.2.2/gcc -I/opt/build/gcc-4.2.2/gcc/. -I/opt/build/gcc-4.2.2/gcc/../include -I/opt/build/gcc-4.2.2/gcc/../libcpp/include -I/export/home/dclarke/local/include -I/export/home/dclarke/local/include -I/opt/build/gcc-4.2.2/gcc/../libdecnumber -I../libdecnumber -DL_muldi3 -c /opt/build/gcc-4.2.2/gcc/libgcc2.c -o libgcc/./_muldi3.o Therefore it looks like somehow CFLAGS_FOR_TARGET="-O2 -xstrconst -xildoff -xarch=v7 -xcode=pic32 -xlibmieee -xlibmil -Xa -xregs=no%appl" which if true is certainly bogus, because CFLAGS_FOR_TARGET should not contain flags for the bootstrap compiler, as it's what the newly-built gcc uses when building target libraries, and those are not gcc options. Check your environment for stray values. Brian
