Use of CC_COMPILE and CXX_COMPILE

[Andrew Hughes]

In the Solaris, *BSD and GNU/Linux makefiles, it states:

"# $(CC) is the c compiler (cc/gcc), $(CXX) is the c++ compiler (CC/g++)."

(make/{solaris,bsd,linux}/makefiles/rules.make)

However, both CC_COMPILE and CXX_COMPILE are then defined in the same way.

CC_COMPILE       = $(CC) $(CXXFLAGS) $(CFLAGS)
CXX_COMPILE      = $(CXX) $(CXXFLAGS) $(CFLAGS)

Shouldn't CXXFLAGS only be added to CXX_COMPILE and not CC_COMPILE?

It also appears that C++ flags are being added to $(CFLAGS):

make/solaris/makefiles/gcc.make:CFLAGS += -fcheck-new
make/bsd/makefiles/gcc.make:CFLAGS += -fcheck-new
make/linux/makefiles/gcc.make:CFLAGS += -fcheck-new

We hit this when trying to build some C code (mkbc.c for our ARM32 port)
using $(CC_COMPILE).  Has $(CC_COMPILE) ever been used with C code?
Is there any in HotSpot itself?

Thanks,
