Description Aaron W. LaFramboise 2005-04-06 08:50:21 UTC 
float complex c = 1.if;  // warning: imaginary constants are a GCC extension

This warning is generated when -pedantic is specified.  This creates problems 
with perfectly valid standard C99 code such as the following.

double complex d = I;

No particular placement of __extension__ seems to be able to make this warning 
go away.
