-Replace codes.h with iberror.h (or remove)
-Move gds__vax_integer and gds__event_block* to alt.cpp and isc_ to gds.cpp
-Use ISC_QUAD internally
-Use isc_vax_integer internally
o use predefined macros to test for sys/wait.h, time.h and sys/time.h
o search strcasecmp in libresolv only if strcasecmp and stricmp are not in libc
o use predefined macro AC_SYS_LARGEFILE to determine 64Bit I/O
o determine the alignment of long and double (ALIGNMENT,DOUBLE_ALIGN),
still need to write a test for FB_ALIGN!
