# Global Compile Options
#
# You may set FG_CFLAGS to include any of the following options depending on 
# your environment:
#
# -g           - Compile with debugging symbols
# -Wall        - Enable full compiler warnings
# -O2          - Enable compiler optimization
#
# Other potential compiler optimization flags:
#
# -O3 -fPIC -funroll-loops -mpentium -malign-loops=2
# -malign-jumps=2 -malign-functions=2 -fexpensive-optimizations
# -pedantic -ffast-math

# Platform specific compile options, these should be set with FG_CFLAGS
# below.  These have been predefined for the supported platforms below.
#
# -DUSE_ITIMER - Use setitimer(), getitimer(), and signal() to mimic
#                a real time system and call the flight model routines
#                at a regular interval, rather than between screen updates
#                which can be highly variable.  This can make the flight
#                model calculations much smoother.
#
# -DUSE_FTIME -  Use ftime() to get an accurate current time instead of
#                gettimeofday()
#
# -DUSE_RAND  -  Use rand() instead of random()
