# make file for DJGPP and ndmake 4.5

# problems using DJGPP 1.08 as at 6 Oct 1992
#   1. signal(SIGFPE,...)  not working.   
#      floating point exceptions TERMINATE gnuplot.
#      This is because signal is defined as signal(){} !!!
#   2. graphics sometimes draws the x axis in the wrong place

# The above problems make gnuplot UNUSABLE under DJGPP at present.

# where to place gnuplot.gih helpfile
HELPFILE = gnuplot.gih

# compiler
CCDIR = c:\gcc\bin
CC = $(CCDIR)\gcc
