# User tunable macros

# CFLAGS: options to the C compiler
#
#	-O	optimize
#	-g	include dbx/sdb info
#	-gg	include gdb debugging info; only for GCC (deprecated)
#	-pg	include new (gmon) profiling info
#	-p	include old style profiling info (System V)
#
#	To port GAWK, examine and adjust the following flags carefully.
#	In addition, you will have to look at alloca below.
#	The intent (eventual) is to not penalize the most-standard-conforming
#	systems with a lot of #define's.
#
#	-DBCOPY_MISSING		- bcopy() et al. are missing; will replace
#				  with a #define'd memcpy() et al. -- use at
#				  your own risk (should really use a memmove())
#	-DSPRINTF_INT		- sprintf() returns int (most USG systems)
#	-DBLKSIZE_MISSING	- st_blksize missing from stat() structure
#				  (most USG systems)
#	-DBSDSTDIO		- has a BSD internally-compatible stdio
#	-DDOPRNT_MISSING	- lacks doprnt() routine
#	-DDUP2_MISSING		- lacks dup2() system call (S5Rn, n < 4)
#	-DGCVT_MISSING		- lacks gcvt() routine
#	-DGETOPT_MISSING	- lacks getopt() routine
#	-DMEMCMP_MISSING	- lacks memcmp() routine
#	-DMEMCPY_MISSING	- lacks memcpy() routine
#	-DMEMSET_MISSING	- lacks memset() routine
#	-DRANDOM_MISSING	- lacks random() routine
#	-DSTRCASE_MISSING	- lacks strcasecmp() routine
#	-DSTRCHR_MISSING	- lacks strchr() and strrchr() routines
#	-DSTRERROR_MISSING	- lacks (ANSI C) strerror() routine
#	-DSTRTOD_MISSING	- lacks strtod() routine
#	-DTMPNAM_MISSING	- lacks or deficient tmpnam() routine
#	-DVPRINTF_MISSING	- lacks vprintf and associated routines
#	-DSIGTYPE=int		- signal routines return int (default void)
