Here is a list (in-progress) of the things needs to get Sage to build (and pass most tests) on Cygwin:

These Cygwin packages need to be installed in order for the Sage build to complete.

file, liblapack, liblapack0, liblapack-devel,
and patch (at least on Windows 7 building Sage's spkg patch fails, see #11232)
Prebuilt sage binaries for cygwin are here: http://sage.math.washington.edu/home/wstein/binaries/cygwin/

#9162 -- pynac.pyx use double precision special functions instead of long double (REVISITED)
#9163 -- output of a subtle test in expect.py differs slightly on cygwin
#9165 -- lcalc does not work for elliptic curves on cygwin
#9167 -- importing sage.libs.ecl yields a "no such process" error
#9168 -- ratpoints does not work correctly
#9169 -- a cachefunc.py doctest hangs seemingly forever
#9170 -- get_memory_usage isn't implemented, e.g., because there's no top
#9171 -- some test failures in sagedoc.py
#9172 -- numerical noise in sage/rings/integer.pyx
#9173 -- BSD.py tests behave differently on cygwin, so need to be written to reflect that
#9174 -- robert miller's 2-descent is completely broken on cygwin
#9176 -- various heegner_index errors involving interval arithmetic on cygwin

#11246: flint-1.5.0.p5 extraneous #includes break typedef ulong (needs review)
#11245: on Win7 tar does not unpack cddlib and networkx spkg's right. See the ticket for a workaround.
#11232: patch spkg should not be installed, use Cygwin's (needs review)
#11119: ECL 11.1.1 fails on Cygwin (patches fixing the issues given on the ticket)
#9154: BoehmGC again! (positive review)
#10247: Sage 4.6 has PARI problems on Cygwin (needs review)
#10240: pari-2.4.3.svn-12577.p9 incorrectly checks for the shared library on Cygwin
#11167: Sage 4.7.alpha3 library doesn't build under Cygwin (needs review)
libblas.dll.a is not copied to $SAGE_LOCAL/lib when ATLAS is "installed" (breaks linbox)
Add "#include <time.h>" to src/Singular/Minor.h the in the Singular spkg
Tachyon fails to build due to same failure that was fixed in #7335.
The following files need to be copied "libcliquer.dll -> libcliquer.so", "libflint.dll -> libflint.so", "libntl.dll.a -> libntl.dll"

#9845: lcalc doesn't build on cygwin due to missing time.h include
#9776: Cygwin: GLPK extension module needs to be more explicit in its linking (positive review)
#9146: cygwin: gd doesn't correctly link in libpng with sage-4.4.3.
#8257: gd needs a better version of expr
#7319: gdmodule fails
#7321: numpy fails to build on cygwin due to not using the correct fortran compiler
#8780: Add cephes spkg for Cygwin (provides complex.h amongst other things)
#8192: PolyBoRi needs png12 and z to build on Cygwin.
#8782: pari does not work under Cygwin
#8907: Python should be build with enable-shared
#9050: libntl.dll should be libntl.dll.a
#8542 / #8903: Pynac needs to use a function pointer table.
#7337: PolyBoRi fails to build on cygwin
libflint.dll needs to be libflint.so, or polynomial_integer_dense_flint.pyx needs to know to use the .dll (maybe not a real issue, let's wait an see on this one).
#8642: port detection for the notebook does not work in Cygwin
#8855: sage-env needs to be updated for Cygwin
#8853: fix M_PI_4 in complex_double on Cygwin
#8852: minor doctest fix in fast_eval.pyx for Cygwin
#8850: Cython should link against BLAS instead of ATLAS on Cygwin
#8849: the palp interface throws a (harmless?) OSError on Cygwin
#8848, #8847, #8846, #8845, #8844, #8843
#9067: boehm_gc (still) fails to build on Cygwin
#9166 -- sympow does not work on cygwin (This should be fixed by the patches made for Solaris x86 - see #9703)

gcc on CYGWIN defines a variable __CYGWIN__. So you can use it to #if(n)def stuff.

(I had no problems with that thus far in Vista Premium 32-bit -Alec Mihailovs)

(Alec - Win7 has a newer codebase, so this is not really a proof that we need not worry --- I think we really need to. Dmitrii)
