Hello 

Thank you for your help

At writing your mail I have not noticed your another reply (below) and have not 
tried the new sources.

Ah, OK, now I see the problem.  I checked in the following change.

  http://hg.savannah.gnu.org/hgweb/octave/rev/ec0c445d0d6f

Does that help?


******************

I am now testing the below 

bootstrap.conf: include mkfifo in the module list default tip   changeset | 
files
bootstrap.conf: remove nonexistent "fstat" module       changeset | files
include -I../libgnu in AM_CPPFLAGS      changeset | files

I have perhaps met other problem due to adding -I../libgnu.
Perhaps it is the problem of gnulib in MinGW environments.


I will report in the different post.

Tatsuro
