Re: octave-3.0.0 could not be built on updated mingw

Hello Michael

It seems that win32 api functions might be not detected.  Perhaps something is 
missing.
What's I should to do.  Unfortunately I deleted the previous system completely.
I cannot come back at the moment.

Great thanks to Michael.

You are complete right.
lo-sysdep.cc -> file-ops.h -> str-vec.h -> Array.h -> lo-utils.h -> windows.h
was the same.

After that I checked the config.h and the config.log
**config.h**
/* Define if your system has LoadLibrary for dynamic linking */
/* #undef HAVE_LOADLIBRARY_API */
**config.log
No record exited about HAVE_LOADLIBRARY_API.

I temporary modified the config.h to
+++++++++
/* Define if your system has LoadLibrary for dynamic linking */
/* #undef HAVE_LOADLIBRARY_API */
#define HAVE_LOADLIBRARY_API 1
+++++++++

The build process went well.
However at the startup of Octave

panic: Segmentation violation -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
error: gnu_history::clean_up_and_save: missing file name

What can I do to solve this?
