176 | interfaces that have changed over the years in different versions of the | |
177 | C standard. The behaviour is controlled by linking corresponding | |
178 | values-*.o objects. Each of these objects contain alternate definitions | |
179 | of one or more variables that the libraries use to select which | |
180 | conflicting behaviour they should exhibit. There are two sets of these | |
181 | objects, values-X*.o and values-xpg*.o. | |
182 | ||
183 | The values-X[ac].o objects set the variable _lib_version. The Studio C | |
184 | compilers use values-Xc.o with either -Xc or (since Studio 12.6) | |
185 | -pedantic to select strictly conformant ISO C behaviour, otherwise | |
186 | values-Xa.o. Since -pedantic is a diagnostic option only in GCC, we | |
187 | need to specifiy the -std=c* options and -std=iso9899:199409. We | |
188 | traditionally include -ansi, which affects C and C++, and also -std=c++* | |
189 | for consistency. | |
190 | ||
191 | The values-xpg[46].o objects define either or both __xpg[46] variables, | |
192 | selecting XPG4 mode (__xpg4) and conforming C99/SUSv3 behavior (__xpg6). | |
193 | ||
194 | Since GCC 5, gcc defaults to -std=gnu11 or higher, so we link | |
195 | values-xpg6.o to get C99 semantics. Besides, most of the runtime | |
196 | libraries always require C99 semantics. | |
197 | ||
198 | Since only one instance of _lib_version and __xpg[46] takes effekt (the | |
199 | first in ld.so.1's search path), we only link the values-*.o files into | |
200 | executable programs. */ | |
