[Description]
Checks whether a character is a lowercase, including foreign ones.

[Explanation]
isextlower returns nonzero if <I>c</I> is a lowercase letter, either ordinary ('a' to 'z')
or foreign one (see <A HREF="$$LINK(ctype.h/isfrgnlower)">isfrgnlower</A>), otherwise it returns zero.
It is an inline function which is implemented using GNU C smart macros, which expands to a
medium-sized code.
