Hi,

Would you consider making a release or a tag?

[lexxmark]

I'm upgrading gnu libs now. I hope new release will be available soon

@GitMensch I have a problem during upgrading gnulib.

Especially when I upgraded obstack.h it seems it's not accepting negative numbers for obstack_blank function.
However M4 tool code still uses obstack_blank with negative values in macro.h and caused runtime errors.

I get the most fresh M4 code from https://ftp.gnu.org/gnu/m4/m4-1.4.18.tar.xz
It has both \m4-1.4.18\src\macro.c and \m4-1.4.18\lib\obstack.h files.

Everything seems to be fixed now.

@egorpugin Please check this win_flex_bison-2.5.24.zip

Will make a new release next week.

So the gnulib issue you've seen is solved? Or are some parts not updated?

[egorpugin]

Please check this win_flex_bison-2.5.24.zip

Is it master? I build from sources.

Yes, it's in master now

Yes I upgraded M4 to v1.4.18

The only issue I met is that new M4 uses gl_avltree_oset now and I had to stay with old gl_rbtree_oset because didn't find an new implementation of gl_rbtree_oset which required in other winflexbison code.

[egorpugin]

Works for me.
