02d5824266 Don't bother clearing the Magic string when the magic number
can't be read, since it isn't cleared on other error paths.

130de9c0b4 Don't bother checking canRead() before calling getMagicNumber();
getMagicNumber() does its own error checking.

6523803203 This is horrible. Split the difference, and declare 'environ' on all non-Darwin
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

4f098b68a5 make Program::Execute use posix_spawn on systems that support it,
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

use a ManagedStatic for this because System can't depend on Support.

6220754525 Make clang bootstrap happier on OSX 10.5 by reducing the number of headers
included when using global symbols to ask the linker for the addresses of
various functions.  One of the symbols was actually getting declared by a
header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
declaration in SearchForAddressOfSpecialSymbol().

0f706ab789 Move the extern symbol declarations outside of
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.
