Thanks for the reply.
No, it doesn't work. I get less warnings, but some are still there and 
the assertion failure still remains.

Now GCC tells me the following:

gcc -Wall -Wextra -pedantic -Waggregate-return -Wbad-function-cast 
-Wcast-align -Wcast-qual -Wdeclaration-after-statement 
-Wdisabled-optimization -Wmissing-prototypes -Wnested-externs 
-Wpointer-arith -Wshadow -Wsign-compare -Wstrict-prototypes -Wundef 
-Wwrite-strings -Wunreachable-code  -O2 -DNDEBUG 
-I"G:\root\main\core\Lua\app\Lua-sys\include" -c lfs.c -o lfs.o \
	&& gcc -shared 	-LG:\root\main\core\Lua\app\Lua-sys/bin 
-LG:\root\main\core\Lua\app\Lua-sys/lib -O2 -Wall -pedantic -o lfs.dll 
lfs.o  -llua51 \
	&& strip --strip-unneeded lfs.dll

lfs.c: In function 'file_utime':
lfs.c:597:16: warning: cast from function call of type 'lua_Number' to 
non-matching type 'long int'
lfs.c:598:17: warning: cast from function call of type 'lua_Number' to

lfs.c: In function 'push_invalid':
lfs.c:665:54: warning: unused parameter 'info'

and the failure is still:

assertion failed!
