 9 mike  1.1.2.1 

10 mike  1.1.2.3     5. VxWorks floating points support is broken.
11                   
12                       - printf() prints them as 0.0000, whatever their value.

18                      and FileSystem::canWrite() were reworked to use open()  with O_WRONLY
19                      or O_RDONLY flags.

29 mike  1.1.2.2 
30                   9. gettimeofday() implementation (see Platform_VXWORKS_PENTIUM_GNU.h)
31                      does not have timezone.

32 mike  1.1.2.3 
33                   10. VxWorks fails on host file system after roughly 1000 iterations
34                       of opendir/readir/closedir.
35               
36                   11. Restrictions:
37               
38                           - Repository is read-only (located in /romfs) and must be
39                             built and configured prior to VxWorks image creation.
40               
41                   12. Should VxWorks use the configuration file mechanism.
42               

43 mike  1.1.2.4     13. ftruncate() fails when against host file system.
44               

45 mike  1.1.2.5     14. libnet.a was missing for XSCALE/gnu. Needed to do this to build it:
46               
47                       $ cd /home/WindRiver/vxworks-6.2/target/usr/src/wrn/coreip
48                       $ make CPU=XSCALE TOOL=gnu

50 mike  1.1.2.6     15. Generated reposity increases from 206K to 1.4MB when the
