Building mozilla/nsprpub on QNX 4.24 breaks in unix_errors.c and prstrms.cpp. The following patches fix the breakage (I added these changes to the QNX Tinderbox build): Index: pr/src/md/unix/unix_errors.c =================================================================== RCS file: /cvsroot/mozilla/nsprpub/pr/src/md/unix/unix_errors.c,v retrieving revision 3.12 diff -c -r3.12 unix_errors.c *** unix_errors.c 1999/04/21 21:39:26 3.12 --- unix_errors.c 1999/05/12 04:35:11 *************** *** 42,50 **** --- 42,52 ---- case EAGAIN: prError = PR_WOULD_BLOCK_ERROR; break; + #ifndef QNX case EALREADY: prError = PR_ALREADY_INITIATED_ERROR; break; + #endif case EBADF: prError = PR_BAD_DESCRIPTOR_ERROR; break; Index: lib/prstreams/prstrms.cpp =================================================================== RCS file: /cvsroot/mozilla/nsprpub/lib/prstreams/prstrms.cpp,v retrieving revision 3.3 diff -c -r3.3 prstrms.cpp *** prstrms.cpp 1999/04/21 21:38:06 3.3 --- prstrms.cpp 1999/05/12 04:35:11 *************** *** 49,54 **** --- 49,56 ---- #define _PRSTR_BP m_psb #define _PRSTR_DELBUF(x) /* as nothing */ #define _PRSTR_DELBUF_C(c, x) /* as nothing */ + #elif defined(QNX) + #define PRFSTREAMS_BROKEN #else #define _PRSTR_BP bp // Unix compilers don't believe in encapsulation

Checked in the fix.
