Re: [Plplot-general] PLplot+wxWidgets+MinGW+Windows10

[David B. <stu...@gm...>]

I have the patch but the file changes indicated in the header do not 
match lines the appear in the /mingw/include/stdlib.h.

I'm guessing that I have a different distribution, the one that comes 
with code blocks, and the c/c++ headers are not the same (though 
hopefully do the same thing).

I agree that this is clearly not a widgets issue but I'm still including 
that group since you were able to help so far.  I am very reluctant to 
edit the stdlib.h file I have if the line numbers and sample info do not 
match at all.  Can you confirm which version of MinGW you applied the 
patch to?  Perhaps I will just get that one, or another compiler 
supported by Code Blocks and start over.
