[gentoo-alt] Cygwin: emerge -u system issues

[Al]

Hello,

while bootstrapping PREFIX on Cygwin I now entered the step "emerge -u
system". I plan to post questions related to this in one thread.

This question is about reemerging ncurses and I hope to find some
experience from side of the INTERIX team.

While installing ncurses there is a step that burns down to this failure:

<------------------->
 (cd /home/prefix/gentoo/var/tmp/portage/sys-libs/ncurses-5.7-r5/image//home/prefix/gentoo/usr/bin
&& ln -s tic.exe  infotocap.exe)

      2 [main] bash 2044 child_copy: linked dll data write copy
failed, 0x6CA88000..0x6CA9493C, done 0, windows pid 2044, Win32 error
487
/home/prefix/gentoo/bin/bash: fork: retry: Resource temporarily unavailable
<------------------->

I nearly understand what is happening, but I still haven't a workaround.

What is happening?

During installaton of the newly compiled ncurses "cd" changes into the
image directory. There are three files:

 cygncurses5.dll
 tic.exe
 toe.exe

"Bash" depends on cygncurses5.dll. In the moment "ln" is called  (part
of bash), "bash" forks. It notices that there is the new
cygncurses5.dll in the PATH now, because the current directory is
always in PATH.  It findes out, that this one has a different address.

Certainly this is not a perfect description of what is going on. What
does it examine the new cygncurses5.dll? Why doesn't it simply use
that one, that is already memory. Maybe my explanation is completely
wrong.

I tried to emerge from ash to avoid bash, but that doesn't help. I
think bash is always drawn in by "ln".

Have you been faced with a similar issue on INTERIX? What did you do
as workaround?

Thanks

Al
