If --enable-threads is used, pthread references appear to get auto-imported, -lpthread is not passed to libgcc, and the build fails with undefined references to libpthread in libgcc. This occurs in 32-bit multilib, as well, despite the presence of 32-bit libpthread.a or in 64-bit (multilib disabled or not) libpthread.a or libpthread.dll.a. For example, in Cygwin, 32-bit libgcc: gcc -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DNATIVE_CROSS -W -Wall -Wwrite-stri ngs -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attrib ute -Wold-style-definition -fno-common -DHAVE_CONFIG_H -Wl,--stack,8388608 -o c c1.exe c-lang.o stub-objc.o attribs.o c-errors.o c-lex.o c-pragma.o c-decl.o c-t ypeck.o c-convert.o c-aux-info.o c-common.o c-opts.o c-format.o c-semantics.o c- ppoutput.o c-cppbuiltin.o c-objc-common.o c-dump.o c-pch.o c-parser.o i386-c.o m sformat-c.o c-gimplify.o tree-mudflap.o c-pretty-print.o c-omp.o \ cc1-checksum.o main.o tree-browser.o libbackend.a ../libcpp/libcpp.a . ./libdecnumber/libdecnumber.a ../libcpp/libcpp.a /usr/lib/libintl.a /usr/lib/lib iconv.a ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -lmpc -lmpfr -lgmp /home/Peter/gcc-trunk/build-149397-20090607/./gcc/xgcc -B/home/Peter/gcc-trunk/b uild-149397-20090607/./gcc/ -L/home/Peter/gcc-trunk/build-149397-20090607/x86_64 -w64-mingw32/32/winsup/mingw -L/home/Peter/gcc-trunk/build-149397-20090607/x86_6 4-w64-mingw32/32/winsup/w32api/lib -isystem /home/Peter/gcc-trunk/winsup/mingw/i nclude -isystem /home/Peter/gcc-trunk/winsup/w32api/include -B/usr/x86_64-w64-mi ngw32/bin/ -B/usr/x86_64-w64-mingw32/lib/ -isystem /usr/x86_64-w64-mingw32/inclu de -isystem /usr/x86_64-w64-mingw32/sys-include -m32 -dumpspecs > tmp-specs mv tmp-specs specs /home/Peter/gcc-trunk/build-149397-20090607/./gcc/xgcc -B/home/Peter/gcc-trunk/b uild-149397-20090607/./gcc/ -L/home/Peter/gcc-trunk/build-149397-20090607/x86_64 -w64-mingw32/32/winsup/mingw -L/home/Peter/gcc-trunk/build-149397-20090607/x86_6 4-w64-mingw32/32/winsup/w32api/lib -isystem /home/Peter/gcc-trunk/winsup/mingw/i nclude -isystem /home/Peter/gcc-trunk/winsup/w32api/include -B/usr/x86_64-w64-mi ngw32/bin/ -B/usr/x86_64-w64-mingw32/lib/ -isystem /usr/x86_64-w64-mingw32/inclu de -isystem /usr/x86_64-w64-mingw32/sys-include -m32 -O2 -I../../gcc/../winsup/ w32api/include -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DNATIVE_CROSS -W -Wall -W write-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-d efinition -isystem ./include -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOA T_NOT_NEEDED -g \ -msse -minline-all-stringops -c \ ../../gcc/config/i386/crtfastmath.c \ -o /home/Peter/gcc-trunk/build-149397-20090607/x86_64-w64-mingw3 2/32/libgcc/crtfastmath.o make[1]: Leaving directory `/home/Peter/gcc-trunk/build-149397-20090607/gcc' # Early copyback; see "all" above for the rationale.
