hello all,
has anyone managed to compile DBI on AIX 5.2 with IBM xlc compiler? i
tried and it breaks like this:
...
 xlc -c -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=16384
-I/usr/local/include -q32 -D_LARGE_FILES -qlonglong -O2
-DVERSION=\"1.42\" -DXS_VERSION=\"1.42\"
-I/opt/freeware/lib/perl5/5.6.1/ppc-aix/CORE -DDBI_NO_THREADS DBI.c
"DBI.xs", line 571.5: 1506-045 (S) Undeclared identifier va_alist.
make: 1254-004 The error code from the last command is 1.

va_alist seem to be declared in /usr/include/varargs.h, but including
that did not seem to help.
perl is 5.6.1 (yes, downgraded from default 5.8) from IBM
