#1451 build of bf_test.exe fails for 4.6-branch on windows
Today I check out the recent stable branch source (Latest ChangeLog date 2014-07-30) and tried to build binaries on windows using mingw 32 and 64 bit. The binaries of gnuplot.exe, wgnuplot.exe and wgnuplot_pipes.exe were built flawlessly. However, "make" stopped at building bf_test.exe.

(The errors are the same between 32 and 64 bit build.)
I have confirmed that the above errors do not occur using the source Latest ChangeLog date of which is 2014-07-15.
(Unfortunately I could not get the source tree at 2014-07-28.)
The change on 2014-07-30 might affects the build.
I execute diff to src/eval.c and sys/syscfg.h which are changed between 07-15 and 07-30.
However, I could find the origin.
(As a reference I attached a diff file.)
Interestingly, the error does not occur 5.0 cvs branch although the similar changes are done.

I got the source at 2014-07-15 and replace the src/eval.c or sys/syscfg.h in the latest source.
When I replaced src/eval.c, no error was occurred. While when I replaced sys/syscfg.h, the same error was occurred. The origin of the error is the change of sys/syscfg.h.
The attachment file is working diff from syscfg.h at 2014-07-15. This modification works for both 32 and 64 bits. On 64 bit build, build OS are correctly represented.
The first part of modification on 2014-07-28 seems to be origin the build of bf_test.exe error. I cannot find the reason why modification on 2014-07-28 affects build of bf_test.exe.
I have reverted the 2014-07-28 change to syscfg.h except for the line
define OS ...
The file bf_test.c should be removed or rewritten, since it is now
causing problems on both Windows and linux.
I have confirmed that build on MinGW platfrom works both 32 and 64 bit. Thanks!
bf_test rewritten for version 5
