+sigcontext 構造体の名前を `struct sigcontext' で統一。
+`struct sigcontext_struct' は使わない。
+(compiler.h, configure.in)
+
+0.3.1b リリース。
+
+[19990709]
+
+#include <asm/sigcontext.h> の前に、
+#define sigcontext_struct sigcontext と書いた。
+(compiler.h)
+glibc 2.X では <asm/sigcontext.h> を直接ではなく 
+<sigcontext.h> を include することで上記の置き換え
+(sigcontext_struct -> sigcontext) がなされる。
+しかし libc5 は <sigcontext.h> を持たないため、
+shuJIT のソースでは #include <asm/sigcontext.h> と書きたい。
+
+0.3.1a リリース。

 [19990705]
 
 ELF の FreeBSD (>= 3.0) に対応した。
