While trying to get gPXE to compile on OS X, using a binutils 2.19 i386-elf
cross toolchain, I ran into a very strange error with the assembler.
Specifically, if it comes across division within parentheses, in a
.equ/.byte/.word/.long expression or an immediate operand, it loses track of the
right parenthesis and reports an error.
Simple test case:
<pre>
$ echo '.equ a, (4/2)' | i386-elf-as
{standard input}: Assembler messages:
{standard input}:1: Error: missing ')'
</pre>
This behavior appears on unmodified binutils versions 2.18, 2.19, and 2.19.1. A
native Linux binutils 2.18 does not show the behavior.
