Вычисление простых чисел во время компиляции, ревизия классики.
Я уже публиковал реализацию Решета Эратосфена, в этот раз - реализация более приближенная к классической.

А теперь давайте посмотрим на круги, т.е., какие сообщения выводят разные компиляторы. Ведь тема информативности/запутанности вывода компиляции - давольно актуальная тема в контексте ошибок в шаблонах.
Вот, какие компиляторы мне попались под руку (за MS Visual C++ - спасибо Олегу Рябкову!) и сколько они нагенерили вывода компиляции:Компиляторстроксловсимволовскачать файлcomeau-4.3.10.1546288028484enum_comeau-4.3.10.1.txtgcc-3.4.61277603474547enum_gcc-3.4.6.txtgcc-4.5.3300167020538enum_gcc-4.5.3.txtgcc-4.6.216596611130enum_gcc-4.6.2.txtmsvc-2010637327486269176enum_msvc-2010.txtДалее приводятся первый и последний сегменты из вывода об ошибках компиляции.comeau-4.3.10.1
