flex-2.5.31 breaks linux-kernel driver firmware generator

[Nicholas Wourms]

Hi,

I've been using flex-2.5.27 for awhile now, and have had 
very few issues with it.  However, when I upgraded flex to 
2.5.31, I discovered that some of the firmware generators in 
 the linux-2.5/2.4 series kernel would no longer compile. 
Specifically, the Adaptec AIC-7??? firmware driver source 
would give me the following error:

aicasm_scan.l: In function `expand_macro':
aicasm_scan.l:522: error: `yytext_ptr undeclared...[SNIP]

It is important to note that reverting to flex-2.5.27 
results in a successful compile.  This can be reproduced 
every time.  Is there a problem with flex or with the aicasm 
source files?  If you want to reproduce this, please use a 
2.4.21-pre5+ (or) 2.4.65+ series kernel.

Cheers,
Nicholas
