3.3.2 worked, 3.4.0 started to have problems....

3.4.0 gives a parse error:
: leisner@soyata;gcc-3.4.0 -save-temps -s foo.c 
foo.c:1:10: warning: extra tokens at end of #ident directive

Hi Marty,

Try:
#ident "This is an ident"

And don't forget the -fident switch on your compile line.

--Eljay

using #ident or #pragma ident

[Marty Leisner]

I'm using 3.4.1 on linux

I found documentation on #pragma ident and #ident skimpy -- I tried
to use them and can't have them mark the output files...

Can someone show me an example where these are used?
