Hi, Folks,

Finally, I make dc, bc, diffutl, gnuplot, grep, m4, sed, f2c available.
(SOURCE CODE INCLUDED)  I haven't tested dc and diffutil yet.  Truly speaking,
to check/verify what I have done/modified is really a brain-damage work.

Please anonymous ftp files from "phi.sinica.edu.tw:/pub/djgpp/tools".
All the executable and changed files are put in each subdirectory 'djgpp'. 
If anything wrong please let me know.

* files are compressed by 'lha.exe'
* In f2c, I removed '#define abs...'.
* In gnuplot, I only made a gnu make version of makefile.
* I made 'bc' to look at 'libmath.b' in 3 ways
	1. c:/g/lib/libmath.b
	2. set BC_MATH_FILE=c:/g/lib/libmath.b
	3. libmath.b at current working directory
* I am still testing/modifying tar, shellutil, fileutil, and textutil.
  When they are ok, I will send them to the public as well.
* 'xargs'-like is finished.  It can only take one argument now.
  'ls | xargs wc -l' is ok
  The next step is to make xargs handle '{}'
* floppy backup/restore software status:
  I haven't started to write it.  The following is just a proposal.
  The idea was inspired by split/merge from DJ and users' complaints.
  If such kind of public domain program has been implemented already,
  tell me please; thus, I don't have to write it again.

  (I had planed to use 'dd' in textutil to do the work.)

  A backup/restore program will do

	1. split data to several chunks
	2. take input from files or pipe line
	3. write-error recover
	4. backup any part(chunk)
	4. w/o restore program, we can still use
		a. copy /b
		b. cat
	   to merge data

  usage:
	backup:
	cat xxxx | split -fa:filename -bs1400k 
		backup xxxx into floppies at filesize 1400KB
	tar c *  | split -fa:filename -bs1400k
		backup data from tar
	tar c *  | split -fa:filename -n4 -bs1400k
		backup the 4th chunk on floppy a: w/ filename.004

	restore:
	copy/b xxx.001+xxx.002+.... yyy
	merge -fa:filename | tar x
