[AC21.4] Patch to build on latest Cygwin (1.5.19)

I sent this a couple of days ago, but it never showed up on either list I addressed it to... The patch below fixes a compiler error that occurs when building the latest 21.5 sources from CVS on the latest Cygwin release. Cygwin 1.5.19 has removed the d_ino field from 'struct dirent' since it wasn't used on Cygwin and apparently POSIX doesn't require it to be present. I haven't done a great deal of testing with this patch, but dired seems to work fine with it. Also, I had to disable the new allocator when building as it was causing core dumps. I haven't had much time to look at it, but apparently, SYS_PAGE_SIZE was returning an unrecognized value in init_mc_allocator() which was causing ABORT() to be called from the switch statement at the beginning of the function. I'll try to look at it in a bit more detail in a few days. --Rick Index: src/sysdir.h =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/src/sysdir.h,v retrieving revision 1.7 diff -u -r1.7 sysdir.h --- src/sysdir.h 2002/06/05 09:57:18 1.7 +++ src/sysdir.h 2006/01/19 04:41:47 ＠＠ -62,7 +62,11 ＠＠ Since applying strlen to the name always works, we'll just do that. */ #define NAMLEN(p) strlen (p->d_name) -#define DIRENTRY_NONEMPTY(p) ((p)->d_ino) +#ifdef __CYGWIN__ +# define DIRENTRY_NONEMPTY(p) ((p)->d_name[0] != '\0') +#else +# define DIRENTRY_NONEMPTY(p) ((p)->d_ino) +#endif /* encapsulation: directory calls */
