This is based on an already upstreamed patched that exists in GCC>9.0.
GCC stddef.h relied on the include guards of headers, and those were
changed in netbsd 9.0, so these packages no longer build.
Since we are using a bootstrap GCC, we also need to patch the headers
in the bootstrap fixincludes, patching the package is not sufficient.
Ada part of PR toolchain/54362.
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
I had intended to migrate the ada framework to use gcc6-aux instead of
lang/gcc5-aux, but unfortunately there's been a regression on NetBSD.
It builds and tests perfectly on DragonFly and FreeBSD, but it only
builds on NetBSD. All the ACAT tests that involve tasking fail, but
the cause is unclear. All the modifications used on gcc5-aux for NetBSD
are present in gcc6-aux but pthread destruction results in a segfault.
Since then gcc5-aux support has been improved, so I'm putting this away
for a while. NetBSD has been removed from the platform support list
for now, but I'll review any patches I get to fix NetBSD tasking.
This compiler is based on gcc 6.2 and is primarily used for the Ada
frontend.
