|
|
<p>In GNU C, you may normally use dollar signs in identifier names.
|
||
|
|
This is because many traditional C implementations allow such identifiers.
|
||
|
|
However, dollar signs in identifiers are not supported on a few target
|
||
|
|
machines, typically because the target assembler does not allow them.
