dlls/kernel/process.c breakage due to environ

[Gerald Pfeifer]

My nightly autobuilder failed to build today, after I've had no
problems for several days.  This seems to be due to yesterday's
changes in dlls/kernel:

process.o: In function `build_initial_environment':
  wine/dlls/kernel/process.c:341: undefined reference to `environ'
  wine/dlls/kernel/process.c:357: undefined reference to `environ'
  process.o: In function `build_envp':
  wine/dlls/kernel/process.c:1018: undefined reference to `environ'
  gmake[2]: *** [kernel32.dll.so] Error 1

Part of the fix is the patch below, but this is not sufficient, as
environ simply is non-standard.  On my SuSE 8.2 box, for example,
/usr/include/unistd.h says:

#ifdef __USE_GNU
  extern char **environ;
  #endif

In other words, on GNU/Linux you are just lucky because even if the
symbol is not declared (which is why you need the extern declaration)
it is in the library.

ChangeLog:
Declare environ at the top, not inside functions.
