[issue43241] curses.h: present but cannot be compiled while building with custom CPPFLAGS

[Xuehai Pan]

New submission from Xuehai Pan :

I install python3 with Linuxbrew. All header files have been symlinked to 
"~/.linuxbrew/inlcude". It raises warnings when I building with custom CPPFLAGS.

```

[issue43241] curses.h: present but cannot be compiled while building with custom CPPFLAGS

Xuehai Pan  added the comment:

./configure raised "WARNING: curses.h: present but cannot be compiled" when 
CPPFLAGS="-I. -I/Include -I${HOMEBREW_PREFIX}/include".

./configure found and compiled with ncurses successfully when CPPFLAGS="-I. 
-I/Include -I${HOMEBREW_PREFIX}/include -I$(brew --prefix ncurses)/include"

It's really weird that all headers in "$(brew --prefix ncurses)/include" are 
already symlinked to "${HOMEBREW_PREFIX}/include".
