Check C compiler type (optimization options)
  GNU C (-O3)
Check bzip2 support
  Check for bzip2 in bzip2 directory
  Check if OS already has bzip2 library installed
-- OS supports bzip2 - linking in bzip2
Check for the C preprocessor
Check if we can use asm code
Check for ANSI options
Check for prototypes
Check the handling of const
Check for time_t
Check for size_t
Check for off_t
Check size of UIDs and GIDs
(Now zip stores variable size UIDs/GIDs using a new extra field.  This
 tests if this OS uses 16-bit UIDs/GIDs and so if the old 16-bit storage
 should also be used for backward compatibility.)
  s.st_uid is 4 bytes
  s.st_gid is 4 bytes
-- UID not 2 bytes - disabling old 16-bit UID/GID support
Check for Large File Support
  off_t is 8 bytes
-- yes we have Large File Support!
Check for wide char support
-- have wchar_t - enabling Unicode support
Check for gcc no-builtin flag
Check for rmdir
Check for strchr
Check for strrchr
Check for rename
Check for mktemp
Check for mktime
Check for mkstemp
Check for memset
Check for memmove
Check for strerror
Check for errno declaration
Check for directory libraries
Check for readlink
Check for directory include file
Check for nonexistent include files
Check for term I/O include file
Check for valloc
Check for /usr/local/bin and /usr/local/man
Check for OS-specific flags
Check for symbolic links
