Gawk on Atari has been compiled and tested using gcc compiler (versions 1.4 and 2.2.2) both with and without -mshort flag. Other compilers can be used but if sizeof(pointer) != sizeof(int) this code will not compile correctly with non-ANSI compiler (prototypes and library). Compiled executables were tested and with minor modifications, due to differences in environment and/or shell, succesfully completed at least the following tests: awf, pearls, resub, chem, swaplns, delete, messages, argarray, longwrds, getline, inftest, spiece2top, fstabplus, compare, arrayref, rs, fsrs, rand, fsbs, negexp, ugh2, asgext, anchgsub, splitargv, fieldwidths, ignorecase, posix, manyfiles, igncfs, lisp, regtest, awkpath, reparse, nfset. Nearly all of these test do not require any adjustments to run, but a modified test suite with a driving Makefile (for gulam) is available on a request from Michal Jaegermann, ntomczak@vm.ucs.ualberta.ca, via e-mail. TOS and MiNT ----------- Setup for Atari assumes that gawk will be used under TOS. In particular atari/system.c source is for a system function which nicely cooperates with gulam shell and pipes are simulated with temporary files. If you plan to run gawk under MiNT then you likely want a different system function and real pipes. For that purpose do not define SYSTEM_MISSING in a configuration file and do not define PIPES_SIMULATED in io.c file. Please note that in the later case gawk calls, in gawk_popen(), a function execl() with a hard-coded name of "/bin/sh". You want likely to change that to get a name and some arguments from an environment variable. This was not done here in order to avoid changes which may prove troublesome in a general distribution. Subdirectory ./atari contains also a file textrd.c with a bug fix for old versions of gcc libraries. This bug is currently fixed and the file is not used, but it is left as a convenience for those who may not updated yet their libraries.
