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,

../../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.
