# This is a shell script. It is sourced by the build scripts in the
# various subdirectories to gather system-, compiler-, and OS-specific
# information required for building the Makefiles.
#
# Most variables in this script are interpreted as boolean variables and
# indicate presence or absence of one specific feature. The value "yes"
# is regarded as "true", all other values (including no value or even
# non-existence of the variable) are interpreted as "false".
#
# Do not forget to quote values that contain shell meta syntax.
#
# -----------------------------------------------------------------------
# $system should contain the name of this file. It may be used by some
# of the build scripts to do things that are specific to one single
# type of system.

# availability of the (non-portable) _doprnt function is assumed.
vprintf=yes
# Does the directory(3) library follow the POSIX conventions (i.e.
# requires the <dirent.h> include file and uses "struct dirent")?
# If not, the (obsolete) BSD-style interface with <sys/dir.h> and
# "struct direct" is assumed.
dirent=yes
# Does the system have the random/srandom library functions? If not,
# rand/srand will be used instead.

# Does the system have the index library function? If not, strchr
# will be used.

# (Look into the manual page for access if in doubt.)
include_unistd_h=yes
# Does the system support the POSIX-style sysconf function to determine
# the maximum number of open files per process? If not, set the

# system call is supported. If neither is available, an educated
# guess will be made.
