G_COMPILER = <Compiler Version>

This variable designates a compiler and version. It can be set to:

<pre>
gcc Gnu C/C++ with no suffix.
gcc2 Gnu C/C++ with a version 2 suffix (default is -2.95).
gcc3 Gnu C/C++ with a version 3 suffix (default is -3.4).
gcc4 Gnu C/C++ with a version 3 suffix (default is -4.1).
gccx Gnu C/C++ with a suffix specified by the GCCX_SUFFIX variable.

cl Microsoft C/C++ with no suffix.
cl6 Microsoft C/C++ version 6.
cl7 Microsoft C/C++ version 7.
cl8 Microsoft C/C++ version 8 (visual studio 2005).
cl9 Microsoft C/C++ version 9 (visual studio 2008).
</pre>

The default suffixes for Gnu C/C++ can be overridden by setting:

GCC2_SUFFIX Defaults to: -2.95
GCC3_SUFFIX Defaults to: -3.4
GCC4_SUFFIX Defaults to: -4.1
GCCX_SUFFIX Has no default.

It might be more convenient to set these variables outside the Makefile. Users can set them in their environment or they can create the <code>common/build/site/site.make</code> file to establish site specific variable settings. For this reason it useful to set them in the Makefile using '''"?="''' so they can be overridden with defaults that are dependent on the platform. For example:

<pre>
ifeq ($(GARCH),linux)
G_COMPILER ?= gcc4
endif
ifeq ($(GARCH),WIN32)
G_COMPILER ?= cl9
endif
</pre>
