The problem is that I wanted to set shmmax, NOT shmmaxpgs per se, but it seems that the only place that spells out the relationship between the two parameters --- thereby suggesting the means to adjust shmmax --- is in function shminit, which is rather deeply embedded in the source code tree: file /usr/src/cygwin/winsup/cygserver/sysgv_shm.cc to be precise.
