Sorry to refresh such an old thread, but I just got a choice
to build psqlODBC on Solaris10/Sparc with sunw cc instead
of gcc. I get tons of warnings like this:
"environ.c", line 325: warning: argument #3 is incompatible with prototype:
prototype: pointer to const unsigned char : "environ.c", line 113
argument : pointer to char
The cause is the same as for the "pointers differ in signedness"
under GCC. I can agree with your assertion that "it's not very nice
to remove all warnings" in the sense that using manual casts may
only cover bugs. But fixing the above warning using proper function
prototypes is still desired. A function that expects constant message
strings should declare that parameter as "char *" instead of
"unsigned char *" and it would avoid warnings like the above.
