AIX header file <sys/types.h> defines TRUE and FALSE when _ALL_SOURCE is
defined, leading to the following compiler error with gcc.
Attached patch does fix this problem, (requires regeneration of src/asn1-parse.c).
I don't think renaming "TRUE" to something like "ksbaTRUE" instead would make
more sense.
Thank you!
