There is, of course, a DJGPP port of GNU Grep (v2gnu/grep21b.zip from
the usual DJGPP ftp sites).  I wouldn't call it ``simple'', though.

If you need to glob file names that are passed to a program as its
command-line arguments, then that is already done for you by the DJGPP
startup code.  You say "progname *.c" and the program gets the list of
all the .c files expanded.

If you need to glob a wildcard inside a program, use the library
function `glob'.  Alternatively, you could read the directory with
`readdir' or `findfirst' and `findnext', and test every file with
`fnmatch'.

You need to browse the DJGPP library reference ("info libc" from the
DOS prompt).
