[Bug preprocessor/21250] New: line number 0 for causes GAS to complain

[segher at kernel dot crashing dot org]

powerpc64-linux-gcc -c -o any-file.o any-file.S 
 
results in 
 
any-file.S: Assembler messages: 
any-file.S:1: Warning: line numbers must be positive; line number 0 rejected 
 
as the pre-processed file looks like 
 
# 1 "any-file.S" 
# 0 "<built-in>" 
# 1 "<command line>" 
# 1 "any-file.S" 
...
