## DLL stuff

## We need to determine the following:
##
## MAIN_LD, MAINLD_FLAGS
##   command and flags for loading the main binary so that it will load
##   shared libraries (DLLs) at runtime, also for profiling.
## CPICFLAGS, CXXPICFLAGS, FPICFLAGS
##   flags for compiling C, C++, and Fortran library code
## SHLIB_LD, SHLIB_LDFLAGS
##   command and flags for creating DLLs (which contain object files
##   from a C or Fortran compiler).
## SHLIB_CXXLD, SHLIB_CXXLDFLAGS
##   command and flags for creating DLLs which contain object files from
##   a C++ compiler.  According to autoconf, the C++ compiler/linker
##   must be used for linking in this case (since special C++-ish things
##   need to happen at link time like calling global constructors,
##   instantiating templates, enabling exception support, etc.).
##
## The procedure is as follows.
##   
## * We use applicable values from imake in case its CC is ours.
## * Irrespective of that, we think we know what to do with GNU tools
##   (GNU C, Fortran, and C++ compilers).
## * Then, use platform specific overrides.
## * As a final safeguard, values from the environment (as specified in
##   one of the configuration files or at the configure command line)
##   override anything we figure out in the case of compiler flags; for
##   linker flags (*LDFLAGS), environment settings override our results
##   if the corresponding *LD variable was set, and add otherwise.
##
## NOTE: We do not provide defaults for the *LDFLAGS, taking a defensive
## approach.  In case we cannot figure out {MAIN,SHLIB}_LDFLAGS and the
## user did not provide defaults, an error results.  A warning is given
## if nothing was obtained for SHLIB_CXXLDFLAGS.
