The stock 2.4.33 fails to compile mdb with this error:
cc -I/usr/local/include -L/usr/local/lib -I../../../include -I../../../include -I.. -I./.. -I./../../../libraries/libmdb -I/usr/local/include -L/usr/local/lib -c ./../../../libraries/libmdb/mdb.c -o mdb.o "./../../../libraries/libmdb/mdb.c", line 3514: undefined symbol: top "./../../../libraries/libmdb/mdb.c", line 3514: left operand of "->" must be pointer to struct/union cc: acomp failed for ./../../../libraries/libmdb/mdb.c
The problem is top is defined inside #if MDB_DEBUG but used without the same #if qualifier.
Normally the DPRINTF macro would just expand to ((void) 0) if MDB_DEBUG is not defined, so no, top is not being used without MDB_DEBUG. But looking closer, I see this requires a C preprocessor that supports vararg macros. Don't you have a C99-compatible toolchain on Solaris?
The fix is: /bin/perl -pe '($. == 3514) && s%^%#if MDB_DEBUG\n%' -i libraries/libmdb/mdb.c /bin/perl -pe '($. == 3517) && s%^%#endif\n%' -i libraries/libmdb/mdb.c
In the future, please use unified diff format. Preferably just use "git format-patch" like it says on http://www.openldap.org/devel/contributing.html
We don't make changes in already released code, and line numbers alone are a poor reference in development code.
