Hi, Just ran into an issue which affects gzip, gettext & tar on AIX. The configure tests for wctype.h & checks for the suitability of wctype_t & wctrans_t.
It detects the presence of wctype.h but wctype_t & wctrans_t are unsuitable at which point it tries to use its own bundled copy of wctype.h. The build then fails as there's conflicting types for wctype_t & wctrans_t. In file included from quotearg.c:43: ./wctype.h:724: error: conflicting types for 'wctype_t' /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.2.0/include/ctype.h:119: error: previous declaration of 'wctype_t' was here ./wctype.h:773: error: conflicting types for 'wctrans_t' /usr/include/wctype.h:52: error: previous declaration of 'wctrans_t' was here bundled wctype.h:724 typedef void * wctype_t; bundled wctype.h:773 typedef void * wctrans_t; system wctype.h:52 typedef wint_t (*wctrans_t)(); gcc ctype.h:119 typedef unsigned int wctype_t; Passing ac_cv_header_wctype_h=no to the configure stage works but is a work around for the issue.
