9850090331 Use STDERR_FILENO rather than 2 in debug print statements, so they'll properly go to stderr on GNO. 2014-11-03 19:20:20 -06:00
Stephen Heumann
488a238ad7 Add an implementation of poll() written in terms of select(), to work around the lack of poll() on GNO. 
This is a BSD-licensed poll() implementation by Brian M. Clapper. Its performance characteristics aren't as good as a "native" poll() would be, but this shouldn't be a problem in practice.

051b79efc1 Move all the source files to 15-character ProDOS-compatible file names. 
Dmake gets confused if you use over-15-character file names, so they needed to be shortened to get it to work. While I was at it, I also switched _ to . in the filenames so they're fully ProDOS compatible.

The shell/hush_test directory (not needed to build the code) still uses ProDOS-incompatible file names.

d4b2c3ce8b Various changes for GNO and ORCA/C compatibility. 2014-11-02 18:30:31 -06:00

3577d48e74 Change the ARRAY_SIZE macro to work around an ORCA/C limitation. 2014-11-01 15:47:17 -05:00

2b0d727f39 Include glob implementation from dietlibc. 
GNO doesn't actually implement glob, although it has a header for it. The GNO header is from an old BSD version and is missing some constants we need, so don't use it.

f6c7fdc027 GNO/ORCA compatiblity: remove final comma in enums, and appropriately define stuff that GNO doesn't have in platform.h. 2014-11-01 14:22:47 -05:00

3709307794 Get rid of varargs macros in hush.c. 2014-11-01 11:25:19 -05:00
Stephen Heumann
8f6869ae25 Miscellaneous changes for ORCA/C and GNO compatibility, mainly removing C99isms. 
At this point, ORCA/C can process the main header files, and some smaller source files compile without errors.
