- fix typo in makefiles/info that affected wmake -show-compile-c
- additional safeguard in src/OpenFOAM/Make/options against self-linking.
This is not normally required unless PROJECT_LIBS has been added into
the link stage.
- with the wmake rules we may have some compiler options bound to the
internal compiler variable. For example,
CC = g++ -std=c++11 -m64
c++FLAGS = ...
So shift any flags from CC to CXXFLAGS for the output of
'wmake -show-cxx', 'wmake -show-cxxflags', etc.
This makes it much easier to handle the values correctly elsewhere.
Eg,
CXX="$(wmake -show-cxx)" CXXFLAGS="$(wmake -show-cxxflags)" \
./configure
- can be useful for retrieving the compilation flags for use with other
make systems (eg, cmake)
* wmake -show-compile (C++ not C)
* wmake -show-cxx
* wmake -show-cxxflags
