@lean4: prepare environment before fork

This was done between fork + exec. This reduces lake hangs due to
malloc state inherited by the child.

Bump PKGREVISION.

@lean4: update to 4.33.0.

Lean 4.33.0 concentrates on responsiveness and consolidation: the
editor keeps more of your work while you type, try? can propose
proofs on its own, lia and grind tactics are improved, and Float
stops being an opaque type. Continuing the transparency work of
v4.31.0, it also enables backward.isDefEq.respectTransparency.types
by default — the change most likely to need attention when porting.

@lean4: update to 4.32.2.

Lean 4.32.2 (2026-07-28)

This point release fixes a soundness bug in the kernel.

The issue was discovered by Ramana Kumar and reported by Kiran
Gopinathan.

A malicious meta program can trick the kernel into accepting a
proof of False, or any other theorem. The kernel’s handling of
nested inductive types with phantom type parameters was incomplete
and bypassed the type checker.

The bug can be exploited even when using comparator.

The external checker nanoda does not suffer from the same bug.
However, by the nature of this bug, it is possible to write proof
terms that exploit it and at the same time exploit unrelated bugs
in the external checker, as demonstrated by Kumar with a bug in
nanoda that was (independently) reported and fixed very recently.
We highly recommend users who have to account for malicious proofs
and follow the recommended way to validate proofs to upgrade to
the latest nanoda version as well.

The FRO takes these issues seriously and will invest in the checker
ecosystem, towards more hardening, more testing and more independent
implementations of kernels and checkers.

See issue #14576 for more details on the bug and PR #14577 for the
fix.

@lean4: fix alloca warning (during package build, and 'lake build')

The -std=gnu99 didn't help because alloca() was used in a C++ file.
Replace calls to alloca with __builtin_alloca instead, and get rid of
the forced gnu99.

Bump PKGREVISION.
