## DLL stuff

## We need to determine the following:
##
## MAINLD, MAINLDFLAGS
##   command and flags for loading the main binary so that it will load
##   shared libraries (DLLs) at runtime
## CPICFLAGS, CXXPICFLAGS, FPICFLAGS
##   flags for compiling C, C++, and Fortran library code
## SHLIBLD, SHLIBLDFLAGS
##   command and flags for creating DLLs
##
## The following procedure is as follows.
## *) We think we know what to do if CC is gcc.  Otherwise, try using
##    imake values in case its CC is ours.
## *) Then, use platform specific overrides.
## *) As a final safeguard, values from the environment (as specified in
##    one of the configuration files) override anything we figure out.
