Lua 5.2.0 compile error

["Bryce Simonds" <bsimonds@...>]

Greetings,

On FreeBSD 7.4 I ran into a compile error while compiling Lua 5.2.0 from the
source code:
[bsimonds@carbon ~/src/lua-5.2.0]$ make freebsd
...
gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_LINUX  -c liolib.c
liolib.c: In function 'f_seek':
liolib.c:543: error: 'off_t' undeclared (first use in this function)
liolib.c:543: error: (Each undeclared identifier is reported only once
liolib.c:543: error: for each function it appears in.)
liolib.c:543: error: expected ';' before 'offset'
liolib.c:544: error: 'offset' undeclared (first use in this function)

A quick search through the archives did not reveal to me if this bug has
been reported before or not.

I was able to easily solve this by placing an include to unistd.h in the
liolib.c file.  A short unified diff of the change follows:
