* the array synopsis in the standard uses struct, so why don't we?
* add method empty (demanded by the standard, many more are actually missing)
* consistently use std::size_t instead of size_t (for std::array it should even be std::size_t)
* simplify operator<<
* unify indentation (to 2)
* make_array is a function and not a method
* improve comments on the preprocessor branches (to improve readability)

fix verbose suggestions output
(thanks to Tobias Malkmus)

[[Imported from SVN: r6861]]

add an option to print the sorted list of modules, including the info
if it is a dependency or a suggestion

[[Imported from SVN: r6860]]

actually depmode and mainmode where the same... only compute one of them

[[Imported from SVN: r6859]]

only update the module mode if it not DEPS, which is the

[[Imported from SVN: r6858]]

documentation for _search_module

[[Imported from SVN: r6857]]

cleaner eval/test statements

[[Imported from SVN: r6856]]

just search any module (dependencies and suggestions)
and do the splitting of DEPS and SUGS list afterwards
=> make sure a module is not listed twice

[[Imported from SVN: r6855]]

remove debug output

[[Imported from SVN: r6854]]

print warnings, but continue compilation
(thanks to Tobias Malkmus)

[[Imported from SVN: r6853]]

don't try to install doxygen when documentation is disabled

[[Imported from SVN: r6852]]

don't stop the dependency tracking if suggestion is missing,
just skip this single entry

[[Imported from SVN: r6851]]

tell the user that we skip a suggestion

[[Imported from SVN: r6850]]

add support to run the dependencies in revers order
(necessarry for "make distclean")

[[Imported from SVN: r6849]]

refactored _check_deps handled missing SUGS as fatal error.
now we just ignore SUSG which are not present or don't match the
required version

[[Imported from SVN: r6848]]

sorting modules:
distinguish between the MAIN pass and DEPS/SUGS

[[Imported from SVN: r6847]]

report about suggestions

[[Imported from SVN: r6846]]

set full path for dependencies.m4

[[Imported from SVN: r6845]]

put path into double-ticks to allow spaces etc.

make m4create work with versioned suggestions

[[Imported from SVN: r6840]]

export module name to make --current work properly again

[[Imported from SVN: r6839]]

bug fix in m4create:
- the current module is stored in $mainmod, not $module

[[Imported from SVN: r6838]]

remove obsolete assignment

[[Imported from SVN: r6837]]

avoid parsing suggestions twice

[[Imported from SVN: r6836]]

remove unused code

[[Imported from SVN: r6835]]

fix DEPS and SUGS check invocation

[[Imported from SVN: r6834]]

for some straneg reason the variable module can not be local...

[[Imported from SVN: r6833]]

[[Imported from SVN: r6832]]

- factor out check and version check of dependencies
- reuse for suggestions
- make versioned suggestions work
