### [Tue Nov  2 17:30:48 GMT 2004 : sketch]
### bison's quotearg_buffer_restyled() has issues with certain compilers
### (in particular, SunPro on Solaris/sparc) using optimisation flags.
### The resulting bison with optimisation breaks on at least net/libIDL.
###
.if !empty(PKGSRC_COMPILER:Msunpro)
PKG_HACKS+=		optimisation
BUILDLINK_TRANSFORM+=	rm:-O[0-9]*
.endif

### gcc-4.5.3 in NetBSD/arm 5.99.59 also breaks bison in net/libIDL.
### -O seems enough for workaround in this case.
