?S:i_ndbm:
?S:	This variable conditionally defines the I_NDBM symbol, which
?S:	indicates to the C program that <ndbm.h> exists and should
?S:	be included.
?S:.
?C:I_NDBM:
?C:	This symbol, if defined, indicates that <ndbm.h> exists and should
?C:	be included.
?C:.
?S:i_gdbmndbm:
?S:	This variable conditionally defines the I_GDBMNDBM symbol, which
?S:	indicates to the C program that <gdbm/ndbm.h> exists and should
?S:	be included.  This was the location of the ndbm.h compatibility file
?S:	in RedHat 7.1.
?S:.
?C:I_GDBMNDBM:
?C:	This symbol, if defined, indicates that <gdbm/ndbm.h> exists and should
?C:	be included.  This was the location of the ndbm.h compatibility file
?C:	in RedHat 7.1.
?C:.
?S:i_gdbm_ndbm:
?S:	This variable conditionally defines the I_GDBM_NDBM symbol, which
?S:	indicates to the C program that <gdbm-ndbm.h> exists and should
?S:	be included.  This is the location of the ndbm.h compatibility file
?S:	in Debian 4.0.
?S:.
?C:I_GDBM_NDBM:
?C:	This symbol, if defined, indicates that <gdbm-ndbm.h> exists and should
?C:	be included.  This is the location of the ndbm.h compatibility file
?C:	in Debian 4.0.
?C:.
?S:d_ndbm:
?S:	This variable conditionally defines the HAS_NDBM symbol, which
?S:	indicates that both the ndbm.h include file and an appropriate ndbm
?S:	library exist.  Consult the different i_*ndbm variables
?S:	to find out the actual include location.  Sometimes, a system has the
?S:	header file but not the library.  This variable will only be set if
?S:	the system has both.
?S:.
?C:HAS_NDBM:
?C:	This symbol, if defined, indicates that some form of ndbm.h or compatibility
?C:	include exists, along with the appropriate library.
?C:.
?S:d_ndbm_h_uses_prototypes:
?S:	This variable conditionally defines the NDBM_H_USES_PROTOTYPES symbol,
?S:	which indicates that the ndbm.h include file uses real ANSI C
?S:	prototypes instead of K&R style function declarations. K&R style
?S:	declarations are unsupported in C++, so the include file requires
?S:	special handling when using a C++ compiler and this variable is
?S:	undefined. Consult the different d_*ndbm_h_uses_prototypes variables
?S:	to get the same information for alternative ndbm.h include files.
?S:.
?C:NDBM_H_USES_PROTOTYPES:
?C:	This symbol, if defined, indicates that <ndbm.h> uses real ANSI C
?C:	prototypes instead of K&R style function declarations without any
?C:	parameter information. While ANSI C prototypes are supported in C++,
?C:	K&R style function declarations will yield errors.
?C:.
?S:d_gdbmndbm_h_uses_prototypes:
?S:	This variable conditionally defines the NDBM_H_USES_PROTOTYPES symbol,
?S:	which indicates that the gdbm/ndbm.h include file uses real ANSI C
?S:	prototypes instead of K&R style function declarations. K&R style
?S:	declarations are unsupported in C++, so the include file requires
?S:	special handling when using a C++ compiler and this variable is
?S:	undefined. Consult the different d_*ndbm_h_uses_prototypes variables
?S:	to get the same information for alternative ndbm.h include files.
?S:.
?C:GDBMNDBM_H_USES_PROTOTYPES:
?C:	This symbol, if defined, indicates that <gdbm/ndbm.h> uses real ANSI C
?C:	prototypes instead of K&R style function declarations without any
?C:	parameter information. While ANSI C prototypes are supported in C++,
?C:	K&R style function declarations will yield errors.

?S:	prototypes instead of K&R style function declarations. K&R style
