Bug in as using .intel_syntax ?

[Hans_Ruesing]

Dear Sirs,

I'am using the cygwin version of as GNU assembler version 2.15.90
(i686-pc-cygwin) using BFD version 2.15.90 20040312 on a WIN XP (SP1) PC.

Compiling
-- file tst.s
pushl $(21  << 16) + (249/3)
--------------

succeeds, but compiling

-- file tst1.s
.intel_syntax noprefix
push (21  << 16) + (249/3)
--------------

gives the error

tst.s: Assembler messages:
tst.s:2: Error: Unrecognized token `<<16)+(249/3)'
tst.s:2: Error: Unexpected token `'

Best regards,
Harud Rüsing
