nasm/configure.ac
H. Peter Anvin 4c9132e3a0 compiler.h: include <sys/types.h> 
Apparently, at least on some OS/2 compilers, <sys/types.h> needs to be
included for off_t to be defined.  This seems like a generically good
idea to include this header whenever it is available.

Remove reference to <types.h>.  This was supposedly for MSVC, but
there is no actual evidence that it is useful beyond <sys/types.h>.
