I think true is a defined identifier since this is compiled as c11. tbsaunde@iceball:/src/gcc1-opt$ cat test.c #define FOO true #if !FOO hello #endif tbsaunde@iceball:/src/gcc1-opt$ gcc/xgcc -B gcc/ -E test.c # 1 "test.c" # 1 "<built-in>" # 1 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 1 "<command-line>" 2 # 1 "test.c" hello tbsaunde@iceball:/src/gcc1-opt$ Trev > > Andreas. > > -- > Andreas Schwab, sch...@linux-m68k.org > GPG Key fingerprint = 58CA 54C7 6D53 942B 1756 01D3 44D5 214B 8276 4ED5 > "And now for something completely different."
