I will try this... but i have to get autoconf and built it ( my version is outdated ) and also m4 and perl and...

Perhaps there is a solution directly from configure.in :

    the caching mecanism for "symbol in library" is based on shell variable.
    Perhaps it is possible to reset the concerned 'cache' variable ( ac_cv_lib_proj_pj_init ) to the
    unknown value when the symbol is not found, in the else part of the AC_CHECK_LIB :

    I mean something like :

            AC_CHECK_LIB(proj,pj_init,PROJ_STATIC=yes,PROJ_STATIC=no;ac_cv_lib_proj_pj_init=unset,)

    I don't i it possible to put several instructions in the AC_CHECK_LIB macro.
    I will try if I get a working autoconf.

Thanks for your effort,

Frédéric.
