I have to port some legacy C code to another platform for testing
purposes. I can't modify the code (for configuration management reasons)
and for a reason I won't get into, I have to compile it as C++ code.
However, it is doing lots of implicit pointer casts that the C compiler
allowed. (void* to char*, etc...). Is there anyway compiler switch to
make g++ ignore those errors? THanks,

Hi Kalle,
Your options are:
1) Use a C compiler
2) Modify the code
Implicit pointer casts that are allowed by C are not allowed by C++.
Despite their many similarities, compliant C code is not always compliant C++ code. Where C and C++ part ways is often troubled waters. (Unfortuantely, C99 has widened the gap creating more troubled waters for those who have to have one foot in the C canoe, and another foot in the C++ canoe.)

g++ -x c foo.cpp -o foo.o
HTH,
