MinGW build error 'setenv' was not declared in this scope'

(MinGW, gcc 4.5.2)

../../octave/libgui/src/octave-gui.cc: In function 'int
octave_start_gui(int, char**)':
../../octave/libgui/src/octave-gui.cc:85:29: error: 'setenv' was not
declared in this scope
make[3]: *** [src/src_libgui_src_la-octave-gui.lo] Error 1
make[3]: Leaving directory `/home/Philip/octdev/oct-3.7/libgui'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/home/Philip/octdev/oct-3.7/libgui'

make[1]: Leaving directory `/home/Philip/octdev/oct-3.7'
make: *** [all] Error 2

FWIW, some googling turned up that MinGW (nor MSVC) doesn't have "setenv".
It seems "putenv" is advised.

Suggestions on how to get past this error?

(I found a replacement code snippet tru this thread, but of course I
wouldn't know how to properly implement it in Octave, or even if it is of
any use at all:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27892
)
