I confirm that GCC-6 is not easy to work with: OpenJDK would not build with

OpenJDK, the variables CC and CXX are not honoured! What I have done (as root):
mv /usr/bin/gcc{,.orig}
cat >/usr/bin/gcc << EOF
#!/bin/bash
gcc -std=c99 "\$@"
EOF
mv /usr/bin/g++{,.orig}
cat >/usr/bin/g++ << EOF
#!/bin/bash
gcc -std=c99 "\$@"
EOF
But that's not enough. The compilation goes to completion, but all the
compiled executables segfault
Downgrading to gcc-5.3 allowed to build. Tests are currently running, but at
least, the executables seem to run.
I agree that gcc6 will cause us problems. I needed to rebuild ptlib and
ran into errors due to:
1. Ambiguous overloaded function. I was able to overcome that by
casting an argument to std::string in several places. Fortunately it
is only one file. src/ptlib/unix/svcproc.cxx
2. There is a check for a header that depends on compiler version. It
fails if the minor version is less than 2. That was fixed by adding
|| __GNUC__ >= 5 to the #if statement. include/ptlib/critsec.h
There are also a TON of warnings about deprecated constructs that creates
very noisy output. I was able to turn them off my adding
STDCCFLAGS += -Wno-deprecated-declarations
to make/unix.mak.
It will be easy enough to add these fixes to the existing patch, but I
fear that this will become the rule for a while.
I'll even note that there are warnings about indentation!
