problem compiling sharutils-4.2.1 under Cygwin 1.0

[Steve Kelem]

I'm trying to build sharutils-4.2.1 under Cygwin 1.0 on WinNT 4.0 SP6 on
a Pentium III 550.

It appears to build and compile ok, but fails the first test.

The test is to uudecode testdata, then uuencode the resulting file and
see if they're the same.  They're not.

testdata looks like:
begin 664 test.bin
M``$"`P0%!@<("0H+#`T.#Q`1$A,4%187&!D:&QP='A\@(2(C)"4F)R@I*BLL
M+2XO,#$R,S0U-C<X.3H[/#T^/T!!0D-$149'2$E*2TQ-3D]045)35%565UA9
M6EM<75Y?8&%B8V1E9F=H:6IK;&UN;W!Q<G-T=79W>'EZ>WQ]?G^`@8*#A(6&
MAXB)BHN,C8Z/D)&2DY25EI>8F9J;G)V>GZ"AHJ.DI::GJ*FJJZRMKJ^PL;*S
MM+6VM[BYNKN\O;Z_P,'"P\3%QL?(R<K+S,W.S]#1TM/4U=;7V-G:V]S=WM_@
?X>+CY.7FY^CIZNOL[>[O\/'R\_3U]O?X^?K[_/W^_P``
`
end

When I run the newly compiled uudecode on WinNT, I get a 257 byte file.
When I run uudecode on the same file on Linux, I get a 256 byte file.
cmp (on Linux) reports:
test.bin test.bin.nt differ: char 11, line 1

When I run the newly-compiled uuencode on WinNT, I get the file:
begin 644 test.bin
:``$"`P0%!@<("0H+#`T.#Q`1$A,4%187&!D`
`
end

Any idea what's wrong or how to fix it?

Help!
