* libltdl/m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER) [cygwin*]:
Add w32api to sys_lib_search_path_spec without overriding gcc's
own search path.
Original patch by Yaakov Selkowitz. As he explained:
With gcc4 providing shared libs, it should now perfectly legitimate to
add any of these libs to the libtool link command. Right now, though,
libtool can't find these libraries because $sys_lib_search_path_spec is
hard-coded to ignore it, and libtool will refuse to link against any
library it can't find (even though the linker itself can).
Instead, this patch simply adds /usr/lib/w32api to the default
gcc-specific search path. The m4_if() makes sure that w32api is added
only once, as is done with Darwin a few lines later.
Tested in combination with several other cygwin patches, as part of the
recent cygwin "official" 2.2.7a-N libtool release(s):

No regressions. Okay to push?
