Environment:

Intel Core i5 (64 bit); Linux Fedora Core 14 (64 bit); pcc of 2011/04/01

Description

Code similar to:

#define I (0.f + 1.fi) /* or (1.fi) */
#define FC float _Complex
#define FC_C(r,i) ((FC)((r) + (i)*I))
static FC fc1 = FC_C( 1.f, 1.f );

gets operands of CAST have incompatible types for either definition of I

Even though this error is erroneous, it would fail anyway because pcc cannot do compile-time evaluation of complex numbers yet. This will be added later.

Now gives error message "constant required" instead. No compile-time, only run-time evaluation of complex numbers.
