[Bug-time] GNU Time 1.7.90 - on HP-UX

[Bruno Haible]

Building it on HP-UX 11.31 with 'cc', there are two problems:

1) The autoconfiguration finds

checking whether C compiler handles -Werror -Wunknown-warning-option... yes
checking whether C compiler handles -Wall... yes
checking whether C compiler handles -Wextra... yes
checking whether C compiler handles -Wformat-security... yes
checking whether C compiler handles -Wswitch-enum... yes
checking whether C compiler handles -Wswitch-default... yes
checking whether C compiler handles -Wformat-nonliteral... yes
checking whether C compiler handles -Wunused-parameter... yes
checking whether C compiler handles -Wfloat-equal... yes
checking whether C compiler handles -fdiagnostics-show-option... yes
checking whether C compiler handles -funit-at-a-time... yes
checking whether C compiler handles -Wmissing-format-attribute... yes
checking whether C compiler handles -Wstrict-overflow... yes
checking whether C compiler handles -Wsuggest-attribute=const... yes
checking whether C compiler handles -Wsuggest-attribute=pure... yes

which afterwards leads to warnings for every cc invocation:
