Previously they were treated as identifiers resulting in code
|
||||
generated like C< &0xFFF >.
|
||||
|
||||
We also try to prevent compile-time warnings from large hex integers,
|
||||
the user isn't responsible for the generated code, so we delay those
|
||||
warnings to run-time.

Subject: [PATCH] lib/h2ph.t to test generated t/_h2ph_pre.ph instead of the
|
||||
system one
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The lib/h2ph.t test executes a t/lib/h2ph.pht which requires
|
||||
'_h2ph_pre.ph'. This should find and exercise generated t/_h2ph_pre.ph
|
||||
file. However, it found a loaded _h2ph_pre.ph from system because the
|
||||
interpreter has the './' directory after the system paths in the @INC by
|
||||
default.
|
||||
|
||||
This patch adds '-I./' to the runperl() invocation to prefer the
|
||||
_h2ph_pre.ph generated at build time.
