[otaran]

Steps To Reproduce

1. git clone https://github.com/skvadrik/re2c.git
2. cd re2c
3. git status

Expected Result

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

Actual Result

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   re2c/test/ctx.S.c
    modified:   re2c/test/scanner.S.c

no changes added to commit (use "git add" and/or "git commit -a")

Notes

Reproducible with re2c version 0.15.2.

OS: Apple OS X El Capitan (10.11.1)
Developer Tools: Xcode 7.1.1 (7B1005)

$ git --version
git version 2.6.3

This issue is caused by files ctx.S.c and scanner.S.c which have counterparts ctx.s.c and scanner.s.c (note case of s letter):

By default OS X comes with case-insensitive HFS+ file system, that is why git reports wrong status.

True!

The same issue is on Windows. Fixed by renaming all tests to use lowercase letters only (long opt analogues of uppercase short opts), see this commit: 06fa1d8

I'm glad you noticed the problem. :)
