Bug ID: 115481
Summary: HAVE_* for long double math functions wrong for
avrlibc (target AVR)
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: dv at vollmann dot ch
Target Milestone: ---

possible patch
New versions of avrlibc provide long double math functions, but crossmake.m4
doesn't know about them. The result is that libstdc++ doesn't build due to
duplicate definitions in math_stubs_long_double.cc.
The fix is the same as commit c6c428196d4c76208a0d34aacfa80b57a20f5097 for
AArch64 RTEMS, just at a different place.
This is somewhat related to
