From the Changelog entries since the last Cygwin release 54, looks like all but
OS/2 now behave more like POSIX, using realpath, including Cygwin and Msys -
	http://www.mirbsd.org/mksh.htm#clog
"R56c is a bugfix-only release everyone must upgrade to:
. [komh] Remove redundant OS/2-specific code, clean up others
. [komh, tg] Fix drive-qualified (absolute and relative) DOS-style path support
in realpath functionality, partially other places
. [tg] Don’t substitute ${ENV:-~/.mkshrc} result again
. [tg] Improve OS/2 $PATH (et al.) handling, drive-relative paths
...
R56 is a bugfix release with some experimental fixes:
...
. [komh] Exclude FAT/HPFS/NTFS-unsafe tests on OS/2 (and Cygwin/MSYS)
...
R55 is mostly a feature release with summary bugfixes:
...
. [tg] Add new standard variable PATHSEP (‘:’, ‘;’ on OS/2)
...
. [tg] Introduce build flag -T for enabling “textmode” on OS/2 (supporting CR+LF
line endings, but incompatible with mksh proper)
. [tg] Merge mksh-os2
