### 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.
##
## Note also that some systems (notably AIX) do not allow for unresolved
## symbols at link time. For such systems, we link against -lm (in case
## it exists) when building a shlib module via SHLIB_LIBADD.
