em libmon vanished decades ago (or never existed), and also ass appears to have
a different idea of what the em opcodes are to everything else and gets
confused.
If feof(fp) or ferror(fp) was set, then our libc returned EOF for all
later reads without trying to read. Our libc now behaves like BSD
(and probably Illumos and musl) by checking only feof(fp). For
difference, glibc doesn't check feof(fp).
I described the difference between our libc and BSD libc in
https://sourceforge.net/p/tack/mailman/message/35430300/
@hexcoder- reported in https://github.com/davidgiven/ack/issues/57
that our getpw() has bugs.
I don't fix these bugs, because Illumos and Linux manual pages say
that getpw() is obsolete. The function can overflow its buffer, so it
is never safe to use. Our libc did not build getpw().
This malloc.h might get confused with the private malloc.h in our
libc. C programs should #include <stdlib.h> for malloc().
This tgmath.h has no useful content, and never worked because
complex.h is missing.
Touch build.lua (by deleting some whitespace) so the *.h globs see
the deletions.
These functions are in POSIX; hypot() is in C99. Also build cabs()
because it rides with hypot(), but don't declare cabs() in any header
file, because our compiler can't parse C99 "double complex" type.
Touch build.lua so it sees that .c files moved.
This undoes part of bfeb736, and returns to using DBL_MAX_EXP and
DBL_MIN_EXP from float.h.
Add a dependency on math/localmath.h and other local header files so
libc is rebuilt when those headers change.
This restores the correct values of DBL_MAX, DBL_MIN_EXP, and related
constants. This fixes some range checks within libc, causing
atof("-36e90") and atof("1.44e-288") to return the correct values.
directories --- wrangling descr files was too hard. C programs can be built
for cpm, pc86, linux386, linux68k!

These files "magically reappeared" after the conversion from CVS to
Mercurial. The old CVS repository deleted these files but did not
record *when* it deleted these files. The conversion resurrected these
files because they have no history of deletion. These files were
probably deleted before year 1995. The CVS repository begins to record
deletions around 1995.
These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted. There is no way to fix
this, because the CVS repository provides no dates of deletion.
