[gcc-2.3.1 sparc-sun-sunos4.1]

gcc -U doesn't work properly:

143!% cat florp.c
#ifdef FLORP
THIS SHOULD APPEAR ONLY IF FLORP IS DEFINED
#endif
144!% /usr/local/bin/gcc-2.2.2/gcc -v -DFLORP -UFLORP -E florp.c
Reading specs from /usr/local/lib/gcc-2.2.2/gcc-lib/sun4/2.2.2/specs
gcc version 2.2.2
 /usr/local/lib/gcc-2.2.2/gcc-lib/sun4/2.2.2/cpp -lang-c -v -DFLORP -UFLORP -undef -D__GNUC__=2 -Dsparc -Dsun -Dunix -D__sparc__ -D__sun__ -D__unix__ -D__sparc -D__sun -D__unix florp.c
GNU CPP version 2.2.2 (sparc)
# 1 "florp.c"



145!% /usr/local/bin/gcc-2.3.1/gcc -v -DFLORP -UFLORP -E florp.c
Reading specs from /usr/local/lib/gcc-2.3.1/gcc-lib/sparc-sun-sunos4.1/2.3.1/specs
gcc version 2.3.1
 /usr/local/lib/gcc-2.3.1/gcc-lib/sparc-sun-sunos4.1/2.3.1/cpp -lang-c -v -DFLORP -UFLORP -undef -D__GNUC__=2 -Dsparc -Dsun -Dunix -D__sparc__ -D__sun__ -D__unix__ -D__sparc -D__sun -D__unix florp.c
GNU CPP version 2.3.1 (sparc)
# 1 "florp.c"

THIS SHOULD APPEAR ONLY IF 1  IS DEFINED

146!% cc -DFLORP -UFLORP -E florp.c
# 1 "florp.c" 
# 3 "florp.c" 

so the handling of -U for gcc-2.3.1 isn't working properly.
