Description of problem:
mysql is failing to build in rawhide, as shown at the koji task mentioned in URL. (The identical sources build fine in F-13.) Investigation shows that the problem is here:
# gcc -E -nostdinc -dI -I./include -I./include/mysql -I./sql -I./include -I./include/mysql -I./sql include/mysql.h
# 1 "include/mysql.h"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "include/mysql.h"
# 47 "include/mysql.h"
include/mysql.h:47:23: fatal error: sys/types.h: No such file or directory
Now, /usr/include/sys/types.h is definitely there, so the error message is a bit bogus in any case. But the real problem is that this is a change from longstanding behavior: the mysql makefile is expecting gcc to bleat but keep on processing.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. gcc -E -nostdinc a file that #include's some system header files.
Aborts after seeing #include <whatever>
Should keep on processing the rest of the input.
But you've told gcc that it shouldn't look up files in /usr/include by -nostdinc.
I think it is clearly mysql that has to be fixed up.
For details see http://gcc.gnu.org/PR15638 and http://gcc.gnu.org/PR44836.
No idea why MySQL is trying to do a poor man's ABI check, when much better ABI check is possible (by analyzing the debug info).
OpenSUSE has abi_test.patch in its mysql-community-server-5.1.46-2.15.src.rpm in Factory, which supposedly allows mysql to build with gcc 4.5+:

Hm, given the discussion in PR15638 it seems clear that gcc upstream won't be interested in undoing this change. I'll whack mysql instead. Thanks for the pointer to a fix approach.
For the benefit of anyone else researching this issue: turns out mysql is already dealing with this at
and the planned fix looks pretty similar to that shown above.
