Torbjörn Granlund says:
I think this is a bug in the gcc 3.4 parser that causes it to
reject regparm attributes.  I have tried to figure out some
alternative syntax that gcc 3.4 could accept, but found nil.

Comment 8 vingo 2007-04-17 06:16:56 UTC 
The problem still exist. My working environment is :
GCC : gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
GMP : the latest release version (gmp4.1)

During compiling, the error will occur.
But I fount if I remove the code "static void __gmpz_aorsmul _PROTO ((REGPARM_3_1 (mpz_ptr w, mpz_srcptr x, mpz_srcptr y, mp_size_t sub))) REGPARM_ATTR (1);" , it can be passed.
So to solve the problem, you can remove the static declaration for the functions that have conflicting type. But I am not sure whether is correct or not. It only make the process of compiling passed.
