Madsen" reported to the debiag bugtracking system. I've verified that the problem is still in version 3.4.3: When using avr-gcc to compile for TinyOS (a operating-system for embedded devices), the nesc-compiler (used to compile TinyOS source code with) needs an assember that allows the use of $ in identifiers. Normaly nesc does this by calling avr-gcc with -B, specifying a path in which an alternative "as" can be found. However, starting with avr-gcc-3.4.0, the -B option no longer causes avr-gcc choose the alternative assembler.
