Patch looks good to me.

Testing a patch with the flag conditionalized on CHOSEN_COMPILER_TYPE.

(In reply to Mark Linimon from comment #3)

This patch is sufficient on powerpc64 but fails on amd64.  What am I missing?
Comment 5 Piotr Kubaj freebsd_committer freebsd_triage 2018-11-28 13:49:13 UTC
(In reply to Mark Linimon from comment #4)
Do you mean it fails with clang or gcc on amd64?
Comment 6 Mark Linimon freebsd_committer freebsd_triage 2018-11-29 11:01:46 UTC
(In reply to Piotr Kubaj from comment #5)

On amd64 I get:

checking whether the C compiler (gcc7 -O2 -pipe  -fnested-functions -fstack-protector -Wl,-rpath=/usr/local/lib/gcc7 -fno-strict-aliasing -std=gnu89   -fstack-protector -Wl,-rpath=/usr/local/lib/gcc7 -L/usr/local/l
ib/gcc7 ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
Comment 7 Piotr Kubaj freebsd_committer freebsd_triage 2018-11-29 14:42:24 UTC
It looks like new GCC supports nested functions without any switch.

We can check for
.if exists(/usr/lib/libstdc++.so)
and only add -fnested-functions if it exists.
