How to compile D-Flat and MemoPad for DOS with Smaller C.

-1. Get Smaller C (with sources) and get it to successfully compile a
    hello-world app. See https://github.com/alexfru/SmallerC.


 0. Recompile Smaller C (core compiler only) to support larger C source files.
    Do (beware, a long command line follows)

    > smlrcc smlrc.c -o smlrcbig[.exe] -DMAX_IDENT_TABLE_LEN=16384 -DSYNTAX_STACK_MAX=8192 -DMAX_CASES=257 -DSTACK_SIZE=256

    Then replace your smlrc[.exe] with smlrcbig[.exe].


  1. Compile D-Flat and MemoPad.
     Do

     > smlrcc @mldflat.txt
     > smlrcc @mmemopad.txt

     This should produce files ldflat.a and memopad.exe.
     In principle, you can now run memopad.exe in DOS, but without help file.


  2. Compile help file tools (huffc and fixhelp) and generate memopad.hlp.

  2.1. If you're doing it in DOS
       Do

       > smlrcc @mhuffc.txt
       > smlrcc @mfixhelp.txt

       This should produce files huffc.exe and fixhelp.exe.
       Then do

       > huffc.exe memopad.txt memopad.hlp
       > fixhelp.exe memopad

       This should produce memopad.hlp for memopad.exe.

  2.2. If you're doing it in Windows
       Do

       > smlrcc -DBUILD_FULL_DFLAT -o huffc.exe huffc.c htree.c
       > smlrcc -DBUILD_FULL_DFLAT -o fixhelp.exe fixhelp.c decomp.c

       This should produce files huffc.exe and fixhelp.exe.
       Then do

       > huffc.exe memopad.txt memopad.hlp
       > fixhelp.exe memopad

       This should produce memopad.hlp for memopad.exe.

  2.3. If you're doing it in Linux (I haven't tested this on Linux yet)
       Do

       > smlrcc -DBUILD_FULL_DFLAT -o huffc huffc.c htree.c
       > smlrcc -DBUILD_FULL_DFLAT -o fixhelp fixhelp.c decomp.c

       This should produce files huffc and fixhelp.
       Then do

       > ./huffc memopad.txt memopad.hlp
       > ./fixhelp memopad

       This should produce memopad.hlp for memopad.exe.

  3. Done! You got memopad.exe and memopad.hlp and can run MemoPad in DOS.
