Each PRG file's preprocessor instance was set up with only its OWN
directory on the include search path (`filepath.Dir(prgFile)`).
That worked for self-contained files but broke any multi-file
build where one PRG `#include`s a header that lives next to a
SIBLING PRG — the other file's directory wasn't on the path, so
the include silently failed and PP just skipped it ("// #include
\"FiveSqlDef.ch\" — not found (skipped)").
This was the root cause behind test_sql_standards's mass-failure
pattern. The test does
#include "FiveSqlDef.ch"
...
Assert( ..., h["columns"][1][1][1] == ND_FN .AND. ... )
`FiveSqlDef.ch` lives in `_FiveSql2/src/` (next to TSqlExecutor.prg
and friends), but the test source sits in `_FiveSql2/test/`.
Building with `./five build _FiveSql2/test/test_sql_standards.prg
_FiveSql2/src/*.prg` should resolve the header from a sibling
input file's directory — but only the test's own dir was searched,
so ND_FN / ND_LIT / ND_BIN / ND_UNI all stayed undefined and the
identifiers fell through to runtime memvar lookup, returning NIL.
Every assertion that compared against the constants therefore
silently failed (24 / 64 passing because non-constant assertions
still worked).
buildMultiPRGWithIncludes now seeds the user-include list with the
directory of every input PRG before handing off to buildMultiPRG.
A test under one directory can now resolve a `#include` that lives
next to a sibling source file in the same multi-file build.
Result: test_sql_standards goes from 24 / 64 to **64 / 64**. The
parser was already correct end-to-end — every SQL:2003-2023
construct it had been advertising actually worked; the test just
couldn't read the constants it was asserting against.
Wired test_sql_standards into the std.ch runner with a per-test
override so it picks up the FiveSql2 src files. Suite stands at
17/17.
Other gates green:
go test ./... : PASS
FiveSql2 SQL:1999 : 43/43
FiveSql2 standards : 64/64 (was 24/64)
Harbour compat : 56/56
std.ch suite : 17/17
FRB suite : 7/7
