Bug #3260: Can't build Ruby with SunStudio on sparc Solaris
http://redmine.ruby-lang.org/issues/show/3260

起票者: Yuki Sonoda
ステータス: Open, 優先度: Normal
担当者: Yui NARUSE, カテゴリ: ext, Target version: 1.9.2
ruby -v: ruby 1.9.3dev (2010-05-08 trunk 27674) [sparc-solaris2.10]

trunkをsparc solaris上でSunのccでコンパイルした場合、次のエラーが出てext/jsonをビルドできませんでした。

ccache cc -I. -I../../../.ext/include/sparc-solaris2.10 -I../../../../../mri/include -I../../../../../mri/ext/json/generator -DRUBY_EXTCONF_H=￥"extconf.h￥"  -D_FILE_OFFSET_BITS=64  -KPIC -m32 -xO4 -g  -ogenerator.o -c ../../../../../mri/ext/json/generator/generator.c
"../../../../../mri/ext/json/generator/generator.c", line 342: a cast does not yield an lvalue
cc: acomp failed for /export/home/yugui/.ccache/generator.tmp.blade1000dev.home.yugui.jp.18621.i
*** Error code 1
make: Fatal error: Command failed for target `generator.o'
Current working directory /export/home/yugui/dev/ruby/build/1.9.2/ext/json/generator

当該箇所を見ると次のようになってます。
 fb->ptr = (char *) REALLOC_N((long*) fb->ptr, char, required);

このlong*へのキャストってどういう意図で行ってますか?
