24.5; hide-ifdef-mode does not consider #elif defined |
|

Hi,
the hide-ifdef-mode minor mode does not consider "#elif defined"
lines. Example program demonstrating the issue:
#include <stdio.h>
int main()
{
#if defined(_WIN32)
printf("Windows\n");
#elif defined(__unix__)
printf("Unixish\n");
#else
#error unsupported system
#endif
return 0;
}
Trying to collapse only the "#if defined(_WIN32)" part or only the
"#elif defined(__unix__)" part will not work. hide-ifdef-mode should
allow that.
In GNU Emacs 24.5.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.16.6)
of 2015-09-10 on foutrelis
Configured using:
`configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib

--param=ssp-buffer-size=4' CPPFLAGS=-D_FORTIFY_SOURCE=2
LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro'

Thank you for taking time and effort to report this.
I can reproduce this in Emacs 24.5, but not in the current emacs-25
branch that will become Emacs 25.1. So I guess this deficiency was
already fixed, and I'm therefore marking this bug done.
