bglibs: ./installer failure on amd64

Hi, Kurt Roeckx reported a problem with installing bglibs-1.021 on
Debian/amd64.  I'm not sure why this wasn't a problem on other 64bit
architectures, but agree with the suggested fix.

Thanks, Gerrit.

Subject: Bug#313064: bglibs: FTBFS: Segmentation fault during install.
To: [email protected]

Package: bglibs
Version: 1.021-1
Severity: serious

Hi,

Your package is failing to build on amd64 with the following
error:
make[1]: Entering directory `/usr/src/bglibs-1.021/gnu/bglibs-1.021'
./installer
make[1]: *** [install] Segmentation fault
make[1]: Leaving directory `/usr/src/bglibs-1.021/gnu/bglibs-1.021'

For a full buildd log see:
http://amd64.ftbfs.de/fetch.php?&pkg=bglibs&ver=1.021-1&arch=amd64&stamp=1118404555&file=log&as=raw

The build log shows:
instlib/installer.c: In function `main':
instlib/installer.c:125: warning: implicit declaration of function `getenv'
instlib/installer.c:125: warning: assignment makes pointer from integer without
 a cast

You need to include <stdlib.h> to get a good declaration of the
function.  The implicit declaration defaults to returning an int
instead of a pointer, and pointers are a different size on 64 bit
arches.


Kurt
