The gitunsetenv function includes an (redundant) declaration of the
'environ' symbol, which is a pointer to the table of environment
variables. Unfortunately, on MinGW, this provokes sparse to issue
the following warning:
compat/unsetenv.c:5:20: warning: non-ANSI function declaration of \
function '__p__environ'
On MinGW, the <stdlib.h> header defines the 'environ' symbol as a
preprocessor macro (via _environ) which obtains the environ table
pointer via a call to the __p__environ() function.
In order to suppress the warning, we simply remove the redundant
declaration of the 'environ' symbol, since the symbol is already
declared correctly in <stdlib.h> (included via git-compat-util.h).
