# You can define CPPFLAGS on the command line.  Aside from system-specific
# flags, you can define:
#   -DREGEX_MALLOC to use malloc/realloc/free instead of alloca.
#   -DDEBUG to enable the compiled pattern disassembler and execution
#           tracing; code runs substantially slower.
#   -DEXTRACT_MACROS to use the macros EXTRACT_* (as opposed to
#           the corresponding C procedures).  If not -DDEBUG, the macros
#           are used.

# Likewise, you can override CFLAGS to optimize, use -Wall, etc.
