37d6a34e58 MSVC is a nimrod. (All verions 10.0 through 14.1) 
"(4074): error C4146: unary minus operator applied to unsigned type, result still unsigned"
So what?  Many programmers are much better than the typical Microsoft coder.
The C standard GUARANTEES that unsigned arithmetic uses two's complement,
ignores overflow, and the result is what the hardware adder produces.

2c2e108301 PE: fix comparison against a constant value 
... due to size always being assigned to right before this comparison,
and instead check against the RVA and size of the export directory
from the header. (note: this is still stricter than the Windows loader
which ignores all of these except the directory RVA, but if the name RVA
is invalid the PE was probably tampered with).
Change 'offset' to 'RVA' in exception message; this field is always an RVA

c34fe09a79 Revamp --android-shlib 
Android "Oreo" wants to deal with ElfXX_Shdr[].  So splice 4KiB into PT_LOAD[0]
with an "extra" copy of them.  This requires careful relocation processing.
It also costs a page at run time, and an average of a page in the file
(depending on fragmentation at the boundary between r-x and rw- .)

402c885987 Merge branch 'jreiser-elfstub' into devel 
New stub strategy on Linux:  Linux adds too many other segments
to the address space: [vdso], [sigpage], ...; and qemu might
arrange them differently.  Thus the only reliable mappings
are the PT_LOAD of the compressed file itself; all other
address space is unknown!  First, the compressed file uses
.bss to occupy all unused pages up to the original brk(0).
Then at run time, the stub gets another mapping of /proc/self/exe,
and uncompresses the user program on top of the original pages.
[*BSD unchanged for now?]

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.

e7f1e99a5e Merge branch 'jreiser' into devel 
O_BINFO simplifies stubs on linux Elf;
PowerPC64 (big endian: Apple Macintosh G5) and PowerPC* cleanup;
-fpie simplification; shlib for arm64, amd64.

A big merge due to suspending activity on 'devel' branch
during stabilization for release of UPX-3.94.
There were intermediate merges with private branch 'jreiser',
and attempted rebase onto 'devel' did not go well.
Verfication of cases ({ET_EXEC, -fpie, shlib} x {$ARCH}) is in progress.
