Updates to autotools

Adds new function git_branch() to version.c and support to set it. Adds --enable-compiler--warnings (error/yes/no), error is default. Add support for clang sanitizer flags. Fix small issues in units.c, once warnings become errors. Make HDF5 compulsory and stop configure if not found.

Added 1 commit:

• 61492f7c - Add compiler warning flags option --enable-compiler-warnings, default is no.

Added 1 commit:

• f015ca61 - Get compiler warnings to work with Intel compiler and on COSMA

Also added new --enable-compiler-warnings option to add -Wall to compiler flags. To get -Werror use --enable-compiler-warnings=error. The default is to not add these. Any one like these to be on by default?

I would definitely like this to be the default :)

The option to turn it off would definitely be useful for those hacking/testing cases where it is a hassle. The default, however, should be that we write good code ;)

I would also be happy with "-Wall -Werror" as default with the option to disable them if possible.

Added 1 commit:

• 14c8273c - Make HDF5 presence compulsory

Added 1 commit:

• 415910cf - Make --enable-compiler-warnings=error the default

Added 1 commit:

• 27f6ec2c - Stop 'control reaches end of non-void function' warnings

OK, that is now the default. Use --disable-compiler-warnings to switch them off of --enable-compiler-warnings=yes to not have warnings as errors.

I've also made the presence of HDF5 compulsory and fixed up units.c to compile!
