1811714 - Build failure with GCC 13 (missing <cstdint> include)

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Sam James]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/109.0

Steps to reproduce:

1. Build a pre-release of GCC 13.
2. Attempt to build Firefox 109..0.

Actual results:

Build failed with GCC 13 like:

 0:29.52 /var/tmp/portage/www-client/firefox-109.0/work/firefox_build/dist/include/mozilla/gfx/Rect.h:327:47: error: no member named 'int32_t' in namespace 'std'
 0:29.52   float min = (float)std::numeric_limits<std::int32_t>::min();
 0:29.53                                          ~~~~~^
 0:29.53 /var/tmp/portage/www-client/firefox-109.0/work/firefox_build/dist/include/mozilla/gfx/Rect.h:328:47: error: no member named 'int32_t' in namespace 'std'
 0:29.54   float max = (float)std::numeric_limits<std::int32_t>::max();
 0:29.54                                          ~~~~~^
 0:29.54 2 errors generated.

It's normal for compilers to shuffle around internal includes between releases, and indeed Rect.h uses int32_t without includg <cstdint.h>.

Expected results:

Successful build with GCC 13.

There are other issues with GCC 13 but they're not as simple and I figure it makes sense to handle them in another bug given this one has a simple cause & patch.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

GCC 13s libstdc++ reduced its dependency on some headers like <cstdint>,
so it's no longer transitively included through various headers.
Include it explicitly.
