Done that, I wrote 2 macros for autoconf that test whether the CC 
compiler or the CXX compiler accepts that flag.

No, it is not a performance issue, on the windows95/NT platforms we use 
cygwin, which is using egcs for both the c and the c++ compilers. There
was some problem with the LWP user threads and the code the compiler 
added to handle exceptions. This was solved by adding the -fno-exceptions
