[stunnel-users] Compile failure with 4.15

[MeeAGhost]

I ran
./configure --enable-dh --disable-libwrap
then when I try to execute make the build fails:

I checked ctx.c and couldn't see where section and ctx are being
defined inside of the init_dh function nor could I see them defined in
the header files.  Am I missing something?

TIA for any assistance.
