An EXPR argument must be a syntactically valid C expression.
If an EXPR contains commas, you may need to write an extra pair of
parentheses around it, so it appears to be a single argument to the

Arrange for the byte size, alignment, or floating point format
of MODE to be adjustable at run time. EXPR will be executed
once after processing all command line options, and should
evaluate to the desired byte size, alignment, or format.
Unlike a FORMAT argument, if you are adjusting a float format
you must put an & in front of the name of each format structure.
Note: If a mode is ever made which is more than 255 bytes wide,
machmode.h and genmodes.c will have to be changed to allocate
more space for the mode_size and mode_alignment arrays. */
