Supply a path name:
$ peflags --cygwin-heap /bin/git
/bin/git.exe: initial Cygwin heap size: 0 (0x0) MB

$ peflags -v /bin/git
/bin/git:
coff(0x022f[+relocs_stripped,+executable_image,+line_nums_stripped,+local_syms_stripped,+bigaddr,+sepdbg])
pe(0x8000[+tsaware])

$ peflags -d -f -n -i -s -b -W -t -w -l -S -x -X -y -Y -z -v /bin/git
/bin/git: coff(0x022f[-wstrim,+bigaddr,+sepdbg])
pe(0x8000[-dynamicbase,-forceinteg,-nxcompat,-no-isolation,-no-seh,-no-bind,-wdmdriver,+tsaware])

$ peflags --cygwin-heap=2048 /bin/git
/bin/git: initial Cygwin heap size: 2048 (0x800) MB
$ peflags --cygwin-heap=0 /bin/git
/bin/git: initial Cygwin heap size: 0 (0x0) MB

Patch years ago to one doc source line removed "version 1.7.10" but left "since"
