@item
This variable is missing on some platforms:
IRIX 6.5, OSF/1 5.1, mingw.
@item
The address of this variable is not a compile-time constant on some platforms:
Cygwin, mingw.
@item
Native Windows platforms (mingw, MSVC) support only a subset of time
zones supported by GNU or specified by POSIX.  @xref{tzset}.

A more portable way of getting the time zone abbreviation is to use
@code{strftime} with the @code{%Z} format.  @xref{strftime}.
