+Subject: [PATCH 8/9] jdk: musl build fix (use SIGRTMAX rather than __SIGRTMAX)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+__SIGRTMAX is a private glibc symbol, which isn't provided
+by musl, thus failing compilation.
+
+From https://sourceware.org/ml/rda/2005-q4/msg00011.html
+    On a GNU(ish) system, [SIGRTMIN / SIGRTMAX] these macros are defined
+    to call functions which compute the actual minimum and maximum
+    realtime signal numbers.  In particular, this computation will exclude
+    any signals used by the C library for its own purposes.  These signals
+    could include signals related to thread debugging or, more
+    importantly, for thread cancellation.
+[...]
+    [The __SIGRTMIN and __SIGRTMAX] constants represent a hard minumum
+    and maximum.
+
+Patch taken from Alpine Linux:
+    https://git.alpinelinux.org/cgit/aports/tree/community/openjdk8/icedtea-jdk-musl.patch?id=4d34f29dddd3934358df7a9607706d09ae0433c3
+
+Upstream-Status: Inappropriate [musl specific]
