This makes "-G num" parsing ambiguous. * This option is synonymous to -shared, and as such we will * not support it for now. * * Special interest options * * Assembler Option * -Wa,option * * Linker Options * object-file-name -llibrary -nostartfiles -nodefaultlibs * -nostdlib -s -static -static-libgcc -shared -shared-libgcc * -symbolic -Wl,option -Xlinker option -u symbol --image-base * * Directory Options * -Bprefix -Idir -I- -Ldir -specs=file * * Target Options * -b machine -V version * * Please note that the Target Options are relevant to everything: * compiler, linker, assembler, preprocessor. * */ #include "config.h" #include "wine/port.h" #include #include #include #include #include #include #include #include "utils.h" static const char* app_loader_template = "#!/bin/sh\n" "\n" "appname=\"%s\"\n" "# determine the application directory\n" "appdir=''\n" "case \"$0\" in\n" " */*)\n" " # $0 contains a path, use it\n" " appdir=`dirname \"$0\"`\n" " ;;\n" " *)\n" " # no directory in $0, search in PATH\n" " saved_ifs=$IFS\n" " IFS=:\n" " for d in $PATH\n" " do\n" " IFS=$saved_ifs\n" " if [ -x \"$d/$appname\" ];
