Description Sam 2007-02-19 03:51:29 CST

tao_idl passes badly params that contain 2 (or more) escaped double quotation
marks \", it seems to all of them, except the first one of them and therefore
the C preprocessor fails and returns with error.

EXAMPLE (define VER has to be a string in the CODE):

tao_idl -Yp,cpp -DVER=\"1.1\" ../idl/omg/CosNotification.idl
cpp: 1.1: No such file or directory
cpp: warning: '-x c' after last input file has no effect
cpp: no input files
tao_idl: preprocessor "cpp" returned with an error

tao_idl -DVER=\"1.1\" ../idl/omg/CosNotification.idl
1.1:
command line: fatal: cannot open  1.1: No such file or directory
cc: acomp failed for 1
/tmp//tao-idli_zLaqFJ.cpp:
tao_idl: preprocessor "cc" returned with an error

IMHO, the quotations are lost somewhere in ACE_Process::spawn(). Another problem
is that i'm not sure tao_idl handles escaped quotations correctly, it just
doesn't takes care about such format values (as much as i can see from the code).

I'll accept this one for now, although I've downgraded its severity to 'minor' 
since it seems to affect only one preprocessor.

We are considering the adoption of a dedicated preprocessor for the IDL 
compiler, rather than having it use the native one, which practice has led to 
many headaches in the past similar to this one.
