warning: pointer targets in initialization differ in signedness

When compiling various packages using the SUNW0gcc, I am seeing a lot of these

warnings:

This happens when compiling OpenSSL 0.98 against PHP-5.1.4.

Should I be concerned, or is gcc smart enough to figure it out?

# 1

Our testing of openssl 0.9.8 with default flags shows no such warnings.

gcc gives warning for the following cases:

signed char sc;

unsigned char uc;

signed char *sp1 = ≻

signed char *sp2 = &uc;// warning

unsigned char *up1 = ≻// warning

unsigned char *up2 = &uc;

Although older compilers did not give such a warning,

and applications might still work, they are potential errors

or abnormal designs.
