     Syntax:  /Bm memavailable
 
     Use the /Bm option to increase the amount of memory that is
     available to the compiler during its second pass. Use of this
     option is necessary only if you encounter the "Function too large
     to optimize" error message. The default memory limit that the
     compiler works within is 2048K. The <memavailable> argument
     accepts the new amount (in kilobytes) of memory; thus a
     <memavailable> value of 4096 makes 4 megabytes of memory
     available. A space between /Bm and its argument is optional.
