If the name of the timezone has more than a few characters a crash can occur on pentium vxWorks iocs. See ansiTime in the vxWorks reference manual for details about TIMEZONE.
src/libCom/osi/os/default/epicsReadline.c used a char variable to hold the return value from getc(), and compared this against EOF. getc() returns int not char because ANSI C allows char to be unsigned if the architecture finds that easier, thus EOF can never be stored in a char on a PowerPC CPU. char should be changed to int or signed char.
The RTEMS startup routine waits until a time synchronization packet is received from an NTP server. This causes the RTEMS intialization to loop endlessly if there is no NTP server on the network. This problem has been fixed in the CVS version by allowing the initialization to time out after a minute or so and to set the IOC time to January 1, 2001.
