[SoX-devel] Compiler support

[robs <aq...@ya...>]

In order for lsx_debug (etc.) to become thread-safe, it needs to become a variadic
macro.

>From WP:
The GNU Compiler Collection, since 3.0, C++Builder 2006 and Visual Studio 2005 [1]
support variable-argument macros, both when compiling C and C++ code. In addition,
GCC supports variadic macros when compiling Objective C. Sun Studio C and C++ have
had support since Forte Developer 6 update 2 (C++ version 5.3) [1].

The most obvious thing (to me) that this would break is MSVC6 -- would this be
okay?
