I have applied this patch and added implementation and tests for
'get_integer' and 'get_number'.

The usage of 'char **environ' is only a little problematic.
It seems to be speced in POSIX.1, but not in ISO-C.
In http://search.cpan.org/~stas/Env-C-0.06/ there is only an include
switch for _BORLANDC.
It might be a good idea to provide wrappers in 'platform.c' for all
functions accession 'environ'.

The 'unsetenv'-problem, ticket 23025, is another issure related to
'environ'.
