We're running Oracle 11g and trying to compile Pro*C code.  Our makefile
executes the following steps: (1) GNU C preprocessor, (2) Oracle Pro*C
precompiler, (3) GNU C compiler.  When the Pro*C precompiler runs, we encounter
the following error...

Syntax error at line 109, column 8, file /usr/appl/cad/prod/lib/pcc/Connect.pc:
Error at line 109, column 8 in file /usr/appl/cad/prod/lib/pcc/Connect.pc

PCC-S-02201, Encountered the symbol "__const" when expecting one of the
followin
g:

   ... auto, char, const, double, enum, float, int, long,
   ulong_varchar, OCIBFileLocator OCIBlobLocator,
   OCIClobLocator, OCIDateTime, OCIExtProcContext, OCIInterval,
   OCIRowid, OCIDate, OCINumber, OCIRaw, OCIString, register,

   union, unsigned, utext, uvarchar, varchar, void, volatile,
   a typedef name, exec oracle, exec oracle begin, exec,
   exec sql, exec sql begin, exec sql type, exec sql var,
The symbol "exec," was substituted for "__const" to continue.


We've traced this back to gconv.h in which there are several function typedefs
containing parameters of type __const.  Earlier on, we found that __const is
defined within an #ifdef/#else/#endif block in /usr/include/cdefs.h.  In order
to allow __const to be defined, we had to add a -U__GNUC__ switch to the cpp
command (which, as stated earlier, runs before the Pro*C precompiler). 
However, we are running gcc and question whether we really should be undefining
__GNUC__.

Could someone offer some advice regarding this issue?

In addition, I'd like to know if this is the appropriate place to post this
issue?  If not, where should I post this issue instead?
