I'm using latest 1.1.4 cygwin mmap doesn't "work" as unix-world expects it should. on unix, if you want to mmap with MAP_FIXED flag, you must supply address aligned to the page boundary, i.e. address should be x*pagesize. page size on windows is 4096 and test program, which configure script runs, aligns address according to it. windows, otoh, require that address should be aligned to "allocation granularity" which is 64k. if supplied address doesn't match this, and probability that it won't match is 15/16, then windows fails to maf on this address with error 1132 -- "The base address or the file offset specified does not have the proper alignment."
