I want to port Spanish Nethack to my favorite system

If you are not a programmer, this page will be of little use to you.

The problems:

The build sequence for Spanish Nethack is changed somewhat from the English version. This was necessary for two reasons:

A new source file, ctype2.c, is introduced. ctype2.c contains functions that classify characters, equivalent to functions declared in the standard C header ctype.h, but assuming that the character is an 8-bit code in the ISO-8859-1 character set.
One step in the existing build is to scan the monster and object lists and create the files include/onames.h and include/pm.h. These files contain #define symbols based on the names of the objects and monsters. If this step were not changed, the symbols would come out in Spanish, and massive changes to the code would be required.

The solutions:

The files src/monst.c and src/objects.c are changed. Object and monster names are moved into new headers: src/obj-en.h and src/mon-en.h contain the original English names, and src/obj-es.h and src/mon-es.h contain the new names in Spanish.

Each makefile must be changed in the following ways:

src/objects.c must be compiled twice. One compile will produce objects.o or equivalent, and the other will produce obj-en.o; the obj-en.o compile is done with the symbol ENGLISH defined at the command line. Most compilers use -DENGLISH to do this.
src/monst.c must likewise be compiled twice. One compile will produce monst.o or equivalent, and the other will produce mon-en.o; the mon-en.o compile is also done with -DENGLISH or equivalent.
All programs other than nethack.exe or equivalent must link to obj-en.o and mon-en.o instead of obj-es.o and mon-es.o.
ctype2.o or equivalent must be added to the link for nethack.exe or equivalent.

An example:

In case the above explanation is not clear, here are the differences for the MSDOS makefile, sys/msdos/Makefile.GCC, between the Spanish and English versions:

Here is what the changes do:

The change to MAKEOBJS links obj-en.o and mon-en.o to makedefs.exe instead of objects.o and monst.o.
The change to SPLEVOBJS links obj-en.o and mon-en.o to lev_comp.exe instead of objects.o and monst.o.
The change to TEXTIO does the same for tile2bin.exe.
The change to TEXTIO2 does the same for til2bin2.exe.
The change to VOBJ23 adds ctype2.o to the build for nethack.exe.
The change to the monst.o build rule adds mon-es.h to its dependencies.
The change to the objects.o build rule adds obj-es.h to its dependencies.
The new mon-en.o, obj-en.o, and ctype2.o build rules build those files for the programs that need them.

OK, I have Spanish Nethack running on my Illudium Q-36 Explosive Space Modulator.
