The sys/win32/msdev port of plplot doesn't make use of configure, just
nmake as mentioned in the INSTALL.txt file. How did you manage to run
configure? Did you use cygwin?

As I didn't make use of configure I hardwired the compilation options
into the makefile in plplot/sys/win32/msdev. If you'd like to use double
instead of float make the following change and run nmake again:

Makefile with float (i.e. current one):

Makefile with double:

I hope this helps,
