In an attempt to speed up ghostscript 2.4.1 under DOS, I compiled in several
fonts (Helvetica, Helvetica-Bold, Times-Roman, Helvetica-Narrow) in addition
to the Ugly and Courier fonts. The performance improvment was quite dramatic.
My test file consisting of 4 pages of text and boxes took 2'30" to display on
a VGA display before compiling in the fonts and 38" after compiling the fonts.
This test was on a Compaq LTE386s/20 and ghostscript took about 8 seconds just
to start up. (This time is included in the above time.)  The executable went
from 589 KB to 621 KB.

I was unable to get djgpp to compile ghostscript 2.4.1 and broke down and
bought the Watcom C/386 comiler V 9.0 (~$580).  The file watc.mak needed to be
modified slightly and is included below.  I executed this makefile using

wmake -f watc.mak

I also had problems with the font2c program for DOS (it left the UGLY font
name in the other font's C code for one thing) and ended up using the font C
files that I had made on UNIX.  

Now all that I need to do is port Ghostview to Windows :-).

# makefile for Ghostscript, MS-DOS/Watcom C386 platform.
# modified by john schultz for Watcom C386 V 9.0 and including

# ------------------------------- Options ------------------------------- #

###### This section is the only part of the file you should need to edit.

# ------ Generic options ------ #

# Define the default directory/ies for the runtime
# initialization and font files.  Separate multiple directories with \;.
# Use / to indicate directories, not a single \.

GS_LIB_DEFAULT=c:/gs241\;c:/gs241/fonts

# Define the name of the Ghostscript initialization file.
# (There is no reason to change this.)

GS_INIT=gs_init.ps

# Choose generic configuration options.

# Setting DEBUG=1 includes debugging features (-Z switch) in the code.
# Code runs substantially slower even if no debugging switches are set,
# and also takes about another 25K of memory.

DEBUG=0

# Setting TDEBUG=1 includes symbol table information for the Watcom debugger.
# No execution time or space penalty, just larger .OBJ and .EXE files
# and slower linking.

TDEBUG=0

# Setting NOPRIVATE=1 makes private (static) procedures and variables public,
# so they are visible to the debugger and profiler.
# No execution time or space penalty, just larger .OBJ and .EXE files.

NOPRIVATE=0

# ------ Platform-specific options ------ #

# Define the drive, directory, and compiler name for the Watcom C files.
# COMP is the full compiler path name (normally \watcom\bin\wcc386p).
# LINK is the full linker path name (normally \watcom\bin\wlinkp).
# CLINK is the compile-and-link utility full path name (normally
#   \watcom\binb\wcl386).
# STUB is the full path name for the DOS extender stub (normally
#   \watcom\binb\wstub.exe).
# INCDIR contains the include files (normally \watcom\h).
# LIBDIR contains the library files (normally \watcom\lib386).
# Note that INCDIR and LIBDIR are always followed by a \,
#   so if you want to use the current directory, use an explicit '.'.

COMP=c:\w\bin\wcc386p
LINK=wlink
CLINK=c:\w\binb\wcl386
STUB=c:\w\binb\wstub.exe
INCDIR=c:\w\h
LIBDIR=\w\lib386

# Choose platform-specific options.

# Define the processor (CPU) type.  Options are 386 or 486.
# Currently the only difference is that 486 always uses in-line
# floating point.

CPU_TYPE=386

# Define the math coprocessor (FPU) type.  Options are 0, 287, or 387.
# If the CPU type is 486, the FPU type is irrelevant, since the 80486
# CPU includes the equivalent of an 80387 on-chip.
# A non-zero option means that the executable will only run if a FPU
# of that type (or higher) is available: this is NOT currently checked
# at runtime.
#   Code is significantly faster.

FPU_TYPE=387
