Re: missing module dependencies for vasnprintf

[Jarno Rajahalme]

I'm trying to compile octave with GCC 4.4, and thought I have a problem with 
gnulib, so I did make distclean, git pull on gnulib, gnulib-tool --import, 
./configure.

I have now these defined in config.h, after doing the above:

#define NEED_PRINTF_DIRECTIVE_A 1
/* #undef NEED_PRINTF_DIRECTIVE_F */
/* #undef NEED_PRINTF_DIRECTIVE_LS */
/* #undef NEED_PRINTF_DOUBLE */
/* #undef NEED_PRINTF_ENOMEM */
/* #undef NEED_PRINTF_FLAG_GROUPING */
/* #undef NEED_PRINTF_FLAG_LEFTADJUST */
#define NEED_PRINTF_FLAG_ZERO 1
/* #undef NEED_PRINTF_INFINITE_DOUBLE */
#define NEED_PRINTF_INFINITE_LONG_DOUBLE 1
/* #undef NEED_PRINTF_LONG_DOUBLE */
/* #undef NEED_PRINTF_UNBOUNDED_PRECISION */


m4/gnulib-cache looks like this:

I hope this helps. I can try reproduce this after my currently running 
"gnulib-tool --create-megatestdir --with-tests --dir=..." completes. Yesterday 
it failed to complete, and today it has been running for about 5 hours already, 
is this normal?
