# VMS version made by Klaus Reimann <kr@cip.physik.uni-stuttgart.de>,
# revised by Roland B Roberts <roberts@nsrl31.nsrl.rochester.edu>.
# This version is for gcc.

# After constructing gzip.exe with this Makefile, you should set up
# symbols for gzip.exe.  Edit the example below, changing
# "disk:[directory]" as appropriate.
#
# $ gzip   == "$disk:[directory]gzip.exe"
# $ gunzip == "$disk:[directory]gunzip.exe"
# $ zcat   == "$disk:[directory]zcat.exe"

# -DHAVE_SYSUTIME_H	Use <sys/utime.h>
# -DNO_MEMORY_H         Don't use <memory.h>. Not needed if STDC_HEADERS.
# -DNO_STRING_H         Use strings.h, not string.h. Not needed if STDC_HEADERS
# -DRETSIGTYPE=int      Define this if signal handlers must return an int.
# -DNO_SYMLINK          OS defines S_IFLNK but does not support symbolic links

# -DNO_DIR		System does not support readdir()
# -DPROTO		Force function prototypes even if __STDC__ not defined
# -DASMV		Use asm version match.S
# -DMSDOS		MSDOS specific
# -DOS2			OS/2 specific
# -DVAXC		Vax/VMS with Vax C compiler
# -DVMS			Vax/VMS with gcc
# -DDEBUG		Debug code
# -DDYN_ALLOC		Use dynamic allocation of large data structures
# -DMAXSEG_64K		Maximum array size is 64K (for 16 bit system)
# -DRECORD_IO           read() and write() are rounded to record sizes.
# -DNO_STDIN_FSTAT      fstat() is not available on stdin
# -DNO_SIZE_CHECK       stat() does not give a reliable file size
