[Bug bootstrap/37528] New: boostrap failure due to configure problems

["kunzjacq at yahoo dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

doing bootstrap of 20080912 snapshot with options

configure --enable-languages=c,c++,fortran --disable-nls
--without-included-gettext --enable-version-specific-runtime-libs --without-x
--with-system-zlib --enable-interpreter --enable-threads=posix

-------------------------------------------------------------------------------
because of lots of unresolved symbols.
if -lcygwin is added to the link options of the part

/home/seb/gcc-4.4-20080905/build/./gcc/xgcc ... -lshell32,

this compiles fine, but then the next command

-------------------------------------------------------------------------------
ar -r ./shlib/libgcc_s.a.tmp _chkstk.o _ctors.o gthr-win32.o 
-------------------------------------------------------------------------------
fails because gthr-win32.o does not exist.

I fixed this in an improper way by changing gcc\config\i386\t-cygming: 

adding -lcygwin to SHLIB_LC definition fixes first error, and adding 
-------------------------------------------------------------------------------
# We hide calls to w32api needed for w32 thread support here:
LIB2FUNCS_EXTRA = $(srcdir)/config/i386/gthr-win32.c
-------------------------------------------------------------------------------
(taken from t-gthr-win32)
fixes 2nd error.

I guess similar changes should be added is some cygwin-specific place?
