 This directory contains C sourcfiles intended to test deheader, and
 a check against which to compare the output.
-
-Many of these examples are takem from the Single Unix Standard's list
-of section 2 and 3 entry points.  I don't necessarily test anything in
-SuS with a structure- or pointer-to-structure type argument; that will
-fail as it should on any modern compiler because the struct is neither
-defined nor the derived pointer type forward-declared with a stub.  I
-also ignore any header that declares only macros.
-
-SuS things excluded by these criteria:
-
-aio.h     - aio_* entry points for asynchronous input and output
-time.h    - asctime() and asctime_r()
-assert.h  - assert() macro
-syslog.h  - closelog(), openlog(), setlogmask(), syslog()
-rexgexp.h - advance() is tested, compile() is not.
-unistd.h  - confstr(), exec*(), fchdir(), fdatasync() not tested.
-math.h    - cos(), cosh(): these will need <math.h>.
-stdio.h   - ctermid(), fdopen(), feof(), ferror(), fflush(), fgetc() not tested.
-time.h    - ctime_r(), difftime(), and daylight are not tested, but ctime() is.
-ctype.h   - not tested; all the macro defs would be unresolved. 
-stdio.h   - cuserid() not tested; SuS includes <stdio.h>
-ndbm.h    - all functions rely on the DBM datatype
-dirent.h  - all entry points depend on struct dirent.
-libgen.h  - basename() tested, dirname() not.
-stdio.h   - div() not tested; SuS includes <stdio.h>
-dlfcn.h   - dlclose(), dlerror(), dlopen(), dlsym() not tested
-grp.h     - functions not tested, getgrent() depends on <grp.h>
-pwd.h     - functions not tested, getpwent() depends on <pwd.h>
-utmpx.h   - functions not tested, most depend on <utmpx.h>
-math.h    - erf(), erfc(), exp(), expm1(), fabs(), floor(). fmod() not tested.
-stropts.h - fattach(), fdetach() not tested
-time.h    - FD_* macros are not tested
-strings.h - ffs() not tested.
-stdio.h   - fgetpos(), fgets(), fileno(), f*lockfile(), fopen(), not tested.
-wchar.h   - fgetwc(), fgetws(), fwide() not tested.
-fmtmsg.h  - fmtmsg() not tested.
-fnmatch.h - fnmatch() not tested.
-unistd.h  - fork(), fpathconf(), free(), fsnyc(), *truncate() not tested.
-stdio.h   - *printf*, fputc(), fputwc(), fputws(), fread(), fwrite() not tested.
-stdio.h   - freopen(), fscanf(), sscanf(), feek(), fseeko() not tested.
-stdio.h   - fsetpos(), ftell(), ftello(), getc(), getchar() not tested.
-math.h    - frexp(), gamma() not tested.
-sys/statvfs.h - fstatvfs(), statvfs() untested.
-sys/timeb.h   - ftime() not tested.
-sys/ipc.h     - ftok()
-ftw.h     - ftw(), nftw() not tested.
-wchar.h   - fwprintf(), wprintf(), swprintf() not tested.
-wchar.h   - fwscanf(), wscanf(), swscanf() not tested.
-stdio.h   - getc_unlocked(), getchar_unlocked() not tested.
-stdio.h   - putc_unlocked(), putchar_unlocked() not tested.
-
-For other dependencies not tested, see the commented-out lines in deheader's
-dependency table.
