Hi, 

AFAIK, it is ANSI that forbids $ in ids. I'd expect this restriction
to be enabled via -ansi (as per gcc docs.) For whatever reason, the
gcc2 snap included in b18 doesn't pass -$ to cpp with -ansi..

 foo$ gcc -v
 Reading specs from
 c:\usr\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\cygnus-2.7.2-970404\specs
 gcc version cygnus-2.7.2-970404
 foo$ echo 'subl $FOO, %eax' | gcc -E -Wp,-P -DFOO=4 -
 subl $FOO, %eax
 foo$ echo 'subl $FOO, %eax' | gcc -E -Wp,-P -DFOO=4 -ansi -
 subl $FOO, %eax

Suggested workaround: use -Wp,-$

 foo$ echo 'subl $FOO, %eax' | gcc -E -Wp,-P -DFOO=4 -Wp,-$ -
 subl $4 , %eax

HTH,
