Subject: bsd-user: style tweak: move extern to header file
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4b599848a8eac9cb12151c81c8815af2c1e03691;p=qemu.git

bsd-user: style tweak: move extern to header file

extern char **environ has no standard home, so move the declaration from the .c
file to a handy .h file. Since this is a standard, old-school UNIX interface
dating from the 5th edition, it's not quite the same issue that the rule is
supposed to protect against, though.
