Bug ID: 99264 Summary: Ada doesn't build against latest glibc Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada Assignee: unassigned at gcc dot gnu.org Reporter: jakub at gcc dot gnu.org Target Milestone: --- In file included from /usr/include/signal.h:315, from /usr/include/sys/param.h:28, from ../../gcc/system.h:305, from ../../gcc/ada/init.c:71: ../../gcc/ada/init.c:584:18: error: missing binary operator before token "(" 584 | # if 16 * 1024 < MINSIGSTKSZ | ^~~~~~~~~~~ Apparently the latest glibc defines it as sysconf (_SC_SIGSTKSZ) and so it isn't usable in preprocessor.
