# Valid options are as follow:
# -DINLINE_FUNCTIONS if your compiler support inline functions (most do)
# -DDEBUG            prints lots of debugging messages.
# -DDEBUGGER         compiles in the debugger
# -DKBUK             if you have a UK style 102 key keyboard
# -DBIG_ENDIAN       if your computer is big-endian (Sparc, 68000 etc)
# -DLITTLE_ENDIAN    if your computer is little-endian (80x86 etc)
# -DALIGNED_ACCESS   if your computer requires words to be on even boundaries
# -DBIGCASE          If your compiler/computer can handle 256 case switches
#
# -D_HPUX_SOURCE     If you are compiling on an HP
# -DSOLARIS          If you are using Solaris (only 2.3 has been tested)
# -DSGI              If you are using an SGI
# -DRS6000           If you are using an RS6000
#
# Note that when compiling on the RS6000 and SGI using the standard cc compiler
# specifying -O2 to optimise the code results in the emulator crashing. I
# believe this is due to compiler bugs (as the programs run OK without
# optimisation). If anyone can shed light on what the problem is I would be
# eternally grateful.
#
# Not specifying the following will mean the defaults are used. They can be
# overridden in the .pcemurc file
#
# -DBOOT360          Boot from a 360k disk image  file
# -DBOOT720          Boot from a 720k disk image file
# -DBOOT1_44         Boot from a 1.44Mb disk image file
# -DBOOT1_2          Boot from a 1.2Mb disk image file
#
# -DBOOTFILE="xyz"   Boot from disk image "xyz" (default "DriveA")
# -DCURSORSPEED=n    Set cursor flash speed to n frames per flash (default 30)
# -DUPDATESPEED=n    Set screen update speed to n frames per update (default 5)
# 
# Including -fomit-frame-pointer should increase speed a little, but it has
# been known to crash the emulator when running on certain machines (80x86
# based PCs under Linux, and HPs running HPUX).
