25 ?S: This variable contains the list of memory models supported by this
26 ?S: system. Possible component values are none, split, unsplit, small,
27 ?S: medium, large, and huge. The component values are space separated.
30 ?S: This variable contains a flag which will tell the C compiler and loader
31 ?S: to produce a program that will run in separate I and D space, for those
32 ?S: machines that support separation of instruction and data space. It is
33 ?S: up to the Makefile to use this.
36 ?S: This variable contains a flag which will tell the C compiler and loader
37 ?S: to produce a program running with a small memory model. It is up to
38 ?S: the Makefile to use this.
41 ?S: This variable contains a flag which will tell the C compiler and loader
42 ?S: to produce a program running with a medium memory model. If the
43 ?S: medium model is not supported, contains the flag to produce large
44 ?S: model programs. It is up to the Makefile to use this.
47 ?S: This variable contains a flag which will tell the C compiler and loader
48 ?S: to produce a program running with a large memory model. It is up to
49 ?S: the Makefile to use this.
52 ?S: This variable contains a flag which will tell the C compiler and loader
53 ?S: to produce a program running with a huge memory model. If the
54 ?S: huge model is not supported, contains the flag to produce large
55 ?S: model programs. It is up to the Makefile to use this.
60 : see what memory models we can support
63 ?X: We may not use Cppsym or we get a circular dependency through cc.
64 ?X: But this should work regardless of which cc we eventually use.

101 Some systems have different model sizes. On most systems they are called
102 small, medium, large, and huge. On the PDP11 they are called unsplit and
103 split. If your system doesn't support different memory models, say "none".
104 If you wish to force everything to one memory model, say "none" here and
105 put the appropriate flags later when it asks you for other cc and ld flags.
106 Venix systems may wish to put "none" and let the compiler figure things out.
