I managed to recompile autoconf 2.59 and it seems to work. I added several new files for this pascal testsuite. Even these basic tests already add two failures to the testsuite: One from types.exp ptyp 'a simple string' does not recognize this as a string. A second one from hello.exp this is specific to gpc compiler as explained in my previous email, because start does not stop the program at the logical expected first line of the main procedure in the program source.
lib/pascal.exp contains code to look for both gpc and fpc but the result is inconsistent for me: On the bash prompt I find both gpc in /usr/bin and fpc in /usr/local/bin but the expect which function seems to only find gpc :(
I struggled a lot with the expect syntax, and the result is probably far from nice for people used to program that kind of language.
Comments most welcome...

* lib/pascal.exp: New file. * gdb.pascal/types.exp: New file. Simply tests the type of literals, adapted from gdb.fortran/types.exp * gdb.pascal/hello/hello.pas: New file. Simple program printing 'Hello, world!'. * gdb.pascal/hello.exp: New file. Small tests on hello.pas source. * gdb.pascal/Makefile.in: New file. * configure.ac: gdb.pascal sub directory added to list of directories. * configure: Regenerated using autoconf 2.59.
