rmt/Makefile.am does not properly account for $(EXEEXT) in its
rmt_PROGRAMS rule, so GNU make's default rule for rmt.c to rmt compilation
kicks in instead of the desired rmt.c to rmt.exe rules on cygwin.  My
approach to patching this was to fix the definition of PU_RMT_PROG as
follows, although you may decide there is a better approach for patching
this in the Makefile.am instead of the .m4 file:
