Oracle proc Pro*C, g++/c++ compile error due to static const unsigned int sqlctx

Question

I'm using Oracle 8.1.6 for Linux, and 7.3.4 on HP-UX. Compiler is gcc/g++ 2.95.2
In working with the Oracle precompiler on both HPUX and Linux, I've found a problem with the way that the Linux precompiler generates the sqlctx variable.
On linux, the following is generated when you run the precompiler:
static const unsigned int sqlctx = 1;
However, on HPUX, this is the corresponding code:
static unsigned long sqlctx = 10673468;
When you compile the Linux version with g++/c++ or aCC, you get fatal errors of this nature:
SQLSubsystem.cpp:562: passing `const unsigned int *' as argument 2 of `sqlcxt(void **, unsigned int *, sqlexd *, const sqlcxp *)' discards qualifiers
Is there a way to force the output of proc to leave off the const?
If you view the binary file proc, you can find the static unsigned int string listed. So I think it may be an option. However, I can't seem to turn it on.
Thanks-

As for sqlctx:
sqlctx is a module identifier variable. i.e. if your project consists of multiple modules, each sqlctx should have different value.
I have seen this error only on Linux Pro*C starting of 8.1.5 version (have not tested 8.0.5 nor 8.1.6).
Anyway, I really can not understand why this error is not patched already.
As for constness:
I can not tell if there is an option which would solve such issue. I can only advise not to use -Werror option of gcc. It generates about 4-5 warnings per module, but it works ;-))
