🚀 go-pugleaf

I have just installed emx-0.8d (i.e. g++ for OS/2 v2.0), and tried to
make the files in the directory "\emx\test" using "make".  Everything
was O.K. until the compilation of the file "hexdump.c".  The compilation
terminated with the error "`optswchar' undeclared".  This "char"
variable is used without declaration in "hexdump.c".  A look at the code
suggested that "optswchar" should be declared in "getopts.h", but isn't.
A search of all files on the disk only found the string "optswchar" in
the files "hexdump.c" and "libc.a", which suggest that a declaration of
"optswchar" has been omitted somewhere.  Can anyone help me with this?
Thanks in advance for any help/advice.
