gcc won't compile if pkgsrc/security/skey is installed (solaris)

[Richard PALO <richard.palo%baou.fr@localhost>]

Just came across this head-scratching anomaly...

When compiling gcc (here 4.7.2), libiberty/sha1.c bombs out if 
pkgsrc/security/skey is installed as apparently this packages installs a 
sha1.h in ${PREFIX}/include which occludes /usr/include/sha1.h (and 
/usr/include/sys/sha1.h for needed integer types.

Is this a problem with skey, or libiberty which isn't detecting whether
or not (in configure, for example) the sha1.h in the path includes 
sys/types.h or not.

to complete the gcc build, simply deinstall skey and reinstall later if 
need be.

Might this (skey's sha1.h ) cause build problems elsewhere (similar to 
libiberty)?
