GCC allows the @samp{$} character in identifiers as an extension for
most targets. This is true regardless of the @option{std=} switch,
since this extension cannot conflict with standards-conforming
programs. Currently the targets that by default do not permit
@samp{$} are AVR, IP2K, MMIX, MIPS Irix 3, ARM aout, and PowerPC
targets for the AIX and BeOS operating systems.
programs. When preprocessing assembler, however, dollars are not
identifier characters by default.
Currently the targets that by default do not permit @samp{$} are AVR,

You can override the default with @option{-fdollars-in-identifiers} or
@option{fno-dollars-in-identifiers}. @xref{fdollars-in-identifiers}.
