Re: link error of liboctave (MinGW build)

[Tatsuro MATSUOKA]

Hello

With your patch for ..../gnulib/lib/glob.in.h  and updated wctype.in.h in 
gnulib repository, a compile
error related to wctype.h and a link error in liboctave.dll linking related 
glob.h were disappeared.

The remaining error at present is that related 'getlogin'.

I will try the code you mentioned in the gnulib ML as a temporal trial. 

http://gcc.gnu.org/viewcvs/trunk/libgfortran/intrinsics/getlog.c?view=markup
in
http://old.nabble.com/getlogin-on-Windows-systems-to27055535.html 

Thanks!

Tatsuro
