+Subject: [PATCH] bc: use MAKEINFO variable for docs
+
+Use the appropiate MAKEINFO variable rather than the hardcoded makeinfo
+command directly, otherwise missing logic never works.

+Subject: [PATCH] notice read and write errors on input and output
+
+Quoting from the bug report:
+ bc (1.06-19ubuntu1) dapper; urgency=low
+ * Make dc notice read and write errors on its input and output.
+ I grepped for mentions of the strings `putc', `print', `getc',
+ `FILE', `stdin', `stdout' and `stderr' and added calls to new
+ error-checking functions unless it was clear from the
+ immediately-surrounding code that the program was exiting
+ nonzero, or would exit nonzero if the call failed. I ignored
+ hits in lib/getopt*, which seems to pervasively ignore write
+ errors when printing usage messages, in the hope that these
+ were correct. I _think_ I got them all. -iwj.

+Subject: [PATCH] dc: fix exit code of q command
+
+The exit code for "echo q | dc" is 1 for dc-1.4.1;
+while the exit code for "echo q | dc" is 0 for dc-1.4.
+
+Here is the answer from ken@gnu.org:
+dc-1.4 was right. There was a rewrite of a chunk of code for 1.4.1 to
+fix a corner case in the Q command, and somehow the placement of the
+clean-up label for the 'q' command got misplaced on the error-handling
+branch instead of the clean-exit branch. The patch below fixes this
+(it is committed for whenever the next bc/dc release gets made).
+
+Thanks for the report,
+ --Ken Pizzini

- + that the program was exiting nonzero, or would exit nonzero if the
