internal replacement function. Following the changes to make realpath(3) use the
__realpath() syscall these no longer detect broken realpath i.e. produce different
code. Bump REVISION to ensure that users get the new version.
some existing COMPILER lines with arch restrictions etc. In the usual
case this is now using "COMPILER = base-clang ports-gcc base-gcc" on
ports with c++ libraries in WANTLIB.
This is basically intended to be a noop on architectures using clang
as the system compiler, but help with other architectures where we
currently have many ports knocked out due to building with an unsuitable
compiler -
- some ports require c++11/newer so the GCC version in base that is used
on these archirtectures is too old.
- some ports have conflicts where an executable is built with one compiler
(e.g. gcc from base) but a library dependency is built with a different
one (e.g. gcc from ports), resulted in mixing incompatible libraries in the
same address space.
devel/gmp is intentionally skipped as it's on the path to building gcc -
the c++ library there is unused in ports (and not built by default upstream)
so intending to disable building gmpcxx in a future commit.
Add -fbracket-depth=512 because the preprocessed source exceeds the suggested
implementation limit of 256 for nesting levels of parenthesized expressions
within a full-expression as given in Annex B of the C++ standard.
Add a missing <sys/select.h> that previously must have been pulled in by
another header.
