--- Comment #16 from Cary Lewis <cary.lewis at gmail dot com> --- Sorry, here is the output of the command that generates the error during make bootstrap. I appreciate the help very much. Here is the configure command: ../gcc-3.4.3/configure --prefix=/usr/local/gcc-3.4.3x --enable-languages=c,c++ --with-gnu-as + cd /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/libsupc++ + /tmp/gcc-build/gcc/xgcc -save-temps -shared-libgcc -B/tmp/gcc-build/gcc/ -nostdinc++ -L/tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/src -L/tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/src/.libs -B/usr/local/gcc-3.4.3x/i686-pc-sco3.2v5.0.7/bin/ -B/usr/local/gcc-3.4.3x/i686-pc-sco3.2v5.0.7/lib/ -isystem /usr/local/gcc-3.4.3x/i686-pc-sco3.2v5.0.7/include -isystem /usr/local/gcc-3.4.3x/i686-pc-sco3.2v5.0.7/sys-include -fPIC -I/tmp/gcc-3.4.3/libstdc++-v3/../gcc -I/tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/i686-pc-sco3.2v5.0.7 -I/tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include -I/tmp/gcc-3.4.3/libstdc++-v3/libsupc++ -O2 -g -O2 -g -O2 -fPIC -fno-implicit-templates -Wall -W -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -c ../../../../../gcc-3.4.3/libstdc++-v3/libsupc++/eh_alloc.cc -o eh_alloc.o In file included from ../../../../../gcc-3.4.3/libstdc++-v3/libsupc++/eh_alloc.cc:34: /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring: In function `void* std::memchr(void*, int, size_t)': /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring:101: error: `void* std::memchr(void*, int, size_t)' conflicts with previous using declaration `void* memchr(void*, int, size_t)' /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring: In function `char* std::strchr(char*, int)': /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring:107: error: `char* std::strchr(char*, int)' conflicts with previous using declaration `char* strchr(char*, int)' /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring: In function `char* std::strpbrk(char*, const char*)': /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring:113: error: `char* std::strpbrk(char*, const char*)' conflicts with previous using declaration `char* strpbrk(char*, const char*)' /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring: In function `char* std::strrchr(char*, int)': /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring:119: error: `char* std::strrchr(char*, int)' conflicts with previous using declaration `char* strrchr(char*, int)' /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring: In function `char* std::strstr(char*, const char*)': /tmp/gcc-build/i686-pc-sco3.2v5.0.7/pic/libstdc++-v3/include/cstring:125: error: `char* std::strstr(char*, const char*)' conflicts with previous using declaration `char* strstr(char*, const char*)' There are commands in the include files that attempt to undef the various c defines, but undef won't undo a function prototype. Let me know if there any any tests you want me to perform.
