AC_ARG_ENABLE() doesn't really work the way you expect: one argument
is called on *any* invocation. Create simple helper wrappers to get
the effect we really want for boolean options.
Define WINELOADER=/dev/null to prevent autoconf from inadvertently
running Wine and think we are not cross-compiling even if we are. It
is at the very best slow and buys us absolutely nothing.

It turns out that the calculation of "twopwr" in ieee_flconvert_bin()
was more complex than necessary, and wrong in the case of a pure
fraction.

The standard syntax for a phony target in Make is:
target: <dependencies>
.PHONY: target
... however, Watcom WMAKE seems to use
target: <dependencies> .SYMBOLIC
and furthermore, seems to *require* it. Therefore, remove the
"perlreq" target from the automatically distributed region and move it
into the specific region; it should not need to change anyway since
the PERLREQ list itself is still synced.
If it was only a matter of the .SYMBOLIC versus .PHONY token it would
be easy enough to change that in syncfiles.pl, but this syntax change
is big enough that it doesn't make enough sense to worry about.

On Windows we need to use _stati64/_fstati64 in order to handle large

Add a generic facility for generating perfect string hashes, where all
that is needed is an enum and a string table. The existing mechanism
using a custom Perl script wrapped around a module continues to be
available for any use case where this particular approach isn't
sophisticated enough.
Much of this patch comes from renaming "enum directives" to "enum
directive" as a result of the string hash generator expecting a set of
uniform naming conventions.

The 2-operand form was inherently unsafe. Use the 3-operand form
instead, which guarantees that arbitrary filenames are supported.
This also means we can remove a few instances of sysopen() which was
used for exactly this reason, however, at least in theory sysopen()
isn't portable.

Passing an object to nasm_zero() allows us to use it on arrays.
Otherwise the array will decay to a pointer and silently clear only

When we make an artificial RESB instructions (due to isolated

The spec says very clearly the {z} decorator is allowed on memory
operands for the MOVDQ* instructions. Remove special cases from the
code to disallow this case, which had the unfortunate effect of
generating a very uninformative error message.

There is no reason to keep a private copy of the value of

If a displacement is as large as the address size currently in use

Implement the MachO do_dead_strip directive, which sets a flag on the
corresponding section. This as well as subsections_by_symbols are
reimplemented as pragmas; if someone uses the predefined macro they
still get the expected behavior.
However, this allows someone to write:
%pragma macho subsections_by_symbols
... and have it ignored if compiling for, say, ELF.
Also, implement the following section attributes:
zerofill, no_dead_strip, live_support, strip_static_syms
