+Subject: [PATCH] ICU-23120 Fix malloc request larger than PTRDIFF_MAX bytes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+* glibc does not allow allocations that exceed PTRDIFF_MAX bytes:
+  https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=9bf8e29ca136094f73f69f725f15c51facc97206
+* Without this, we get compile failures on 32-bit platforms:
