Cannot compile GNU Hello in outside linux filesystem image

[sunjoong]

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.15063]

• What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)

It's a very simple test. I compiled GNU Hello in linux filesystem image and outside that. In linux filesystem image, I can compile it, but outside that, I cannot comile, with same condition and command but position.

CASE1: Sucess

SUNJOONG-DESKTOP ~ # cd ~
SUNJOONG-DESKTOP ~ # tar xvzf ~/hello-2.10.tar.gz
SUNJOONG-DESKTOP ~ # cd ~/hello-2.10/
SUNJOONG-DESKTOP hello-2.10 # ./configure
SUNJOONG-DESKTOP hello-2.10 # make

CASE2: Fail

SUNJOONG-DESKTOP ~ # cd /mnt/c/Users/sunjoong/Desktop
SUNJOONG-DESKTOP Desktop # tar xvzf ~/hello-2.10.tar.gz
SUNJOONG-DESKTOP ~ # cd /mnt/c/Users/sunjoong/Desktop/hello-2.10/
SUNJOONG-DESKTOP hello-2.10 # ./configure
SUNJOONG-DESKTOP hello-2.10 # make

What is the error you get?

@MikeGitb - In CASE2 only, not in CASE1;

SUNJOONG-DESKTOP hello-2.10 # make

WARNING: 'aclocal-1.14' is missing on your system.
         You should only need it if you modified 'acinclude.m4' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'aclocal' program is part of the GNU Automake package:
         <http://www.gnu.org/software/automake>
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         <http://www.gnu.org/software/autoconf>
         <http://www.gnu.org/software/m4/>
         <http://www.perl.org/>
make: *** [Makefile:1450: aclocal.m4] Error 127

I found why this will happen.

I did not modify 'acinclude.m4' or 'configure.ac' m4 files included by 'configure.ac'.
But, make knew those files were modified because of VFS design.

That's worthy to be called bug because it will make many potential problems.
Now, I understand why that happened and knew @SvenGroot had been self-assigned to this bug,
so I'll close this issue.
