            Bug ID: 118045
           Summary: [15 Regression] libm2iso.so.20.0.0 contains an
                    unresolvable reference to symbol casin (and 171 other
                    similar warnings)
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org
  Target Milestone: ---

trunk 20241214 produced an underlinked libm2iso.so on x86_64-linux-gnu, the
Debian/Ubuntu packaging complaining about

dpkg-shlibdeps: warning:
debian/gcc-snapshot/usr/lib/gcc-snapshot/lib/libm2iso.so.20.0.0 contains an
unresolvable reference to symbol casin: it's probably a plugin
dpkg-shlibdeps: warning: 171 other similar warnings have been skipped (use -v
to see them all)

looks like a missing -lm.
